“What means "holding fast the word of life"? i.e. "being destined to live, being of those that are gaining salvation." Observe how immediately he subjoins the rewards, which are in reserve. Lights [i.e. luminaries], he says, retain the principle of light; so do ye the principle of life. What means "the word of life"? Having the seed of life, i.e. having pledges of life, holding life itself, i.e. "having in yourselves the seed of life," this is what he calls "the word of life." Consequently the rest are all dead, for by these words he signified as much; for otherwise those others likewise would have held "the word of life." "That I may have whereof to glory," he says; what is this? I too participate in your good deeds, he says. So great is your virtue, as not only to save yourselves, but to render me illustrious. Strange kind of "boasting," thou blessed Paul! Thou art scourged, driven about, reviled for our sakes: therefore he adds, "in the day of Christ, that I did not run," he says, "in vain, nor labored in vain," but I always have a right to glory, he means, that I did not run in vain.”

“Above, the Apostle exhorted them to do works of salvation; here he teaches them the manner of doing them. And first he teaches the manner itself; second he assigns the reason for it, at "that you may be," etc. He teaches a twofold manner of doing them, namely without murmuring and without doubting. For works of virtue are most difficult, and in these murmuring has a place. 1 Cor. 10:10: "neither murmur, as some of them murmured, and perished by the destroyer." And lest you doubt whether they are to be done. James 1:6: "for he who hesitates is like a wave of the sea, which is moved by the wind, and carried about," etc. He then gives the reason for this, first on the part of them; second on the part of the Apostle, at "to my glory," etc. Concerning the first, a threefold reason is given. The first, in comparison to the faithful, when he says "that you may be without complaint." Luke 1:6: "walking in all the commandments and justifications of the Lord without complaint," etc. But no one can be without sin, though he can well be without complaint. Hence he admonishes to this. Second, in comparison to God, at "simple," etc. For a son is like the father; but God is simple; hence we should be simple as sons of God, which is, when the intention is toward one thing. James 1:8: "a man double in soul is inconstant in all his ways." Matt. 10:16: "be prudent as serpents, and simple as doves." Third, in comparison to unbelievers, at "without reproach," etc., that is, that they may conduct themselves well toward unbelievers, namely that they be without offense, "in the midst of a nation" that is "depraved," as to evil works, "and perverse," as to unbelief: and this is when they cannot be defamed by them. 1 Tim. 5:14: "give no occasion to the adversary for the sake of reviling." And the reason for this is given, at "among whom," etc. Because however the world may be varied, the lights of heaven remain bright. Matt. 5:14: "you are the light of the world," etc. Shining, not as to essence, for in that way only God is light. John 1:4: "and the life was the light of men," etc. But the saints are not so. John 1:8: "he was not the light," etc. But they are light, insofar as they have something of the light of him who was the light of men, namely of the Word of God shining upon us. And therefore he says "holding fast the word of life," namely the word of Christ. John 6:68: "Lord, to whom shall we go? You have the words of eternal life." Ps. 118:105: "your word is a lamp to my feet," etc. Then he gives the reason on the part of the Apostle, at "to my glory." Second, he makes the reason clear, that subjects ought to act well, also so that it may redound to the glory of their prelates. For it is their glory when subjects are well instructed. Prov. 10:1: "a wise son gladdens the father," etc. 1 Thess. 2:20: "for you are our glory," etc. And this "in the day of Christ," namely when he will bring the faithful with him. And this is for glory on account of two things, namely on account of labor in preaching and on account of the suffering of death which he sustained. And therefore he says "that I have not run in vain, nor labored in vain." By "course" he means preaching, on account of its swiftness, since it went from Jerusalem even to Spain. Likewise "labors," on account of the contradictions and punishments which he endured, and this not in vain, but rather to much fruit. 1 Cor. 15:10: "his grace in me has not been empty." Likewise on account of suffering, at "but if I am also sacrificed." For in converting some, he offers a sacrifice to God, as it were from those whom he converts. But sometimes those offering were killed by tyrants upon the sacrifice, as is found in Luke 13:1. And therefore he says: I offer to God a sacrifice from you. But if it should happen that I too am sacrificed upon this, that is, that on occasion of the sacrifice of your conversion I be killed, I rejoice on my own account. James 1:2: "count it all joy, my brothers, when you fall into various temptations," etc. And I congratulate you that you have faith even with danger to my person, for which also in this you should rejoice. And therefore he says "in the same way, rejoice and congratulate me." Rom. 12:15: "to rejoice with those who rejoice." Then when he says "but I hope," etc., he sets forth his disciples as an example. And first Timothy, second Epaphroditus, at "but necessary," etc. Concerning the first, first he sets forth the sending of Timothy; second he commends him, at "no one," etc.; third he indicates the time of the sending, at "him therefore," etc. He says therefore "I hope," etc. It should be noted that the Apostle had such confidence in God that he attributed even the smallest things to God. 2 Cor. 3:5: "not that we are sufficient to think anything of ourselves as of ourselves, but our sufficiency is from God." The letter is plain. Then he commends him, first from his charity toward them; second from his devotion to the Apostle, at "the proof," etc. And thus a good mediator acts, for he loves the one, and reveres the other. Likewise, first he sets down the commendation; second he explains it, at "for all seek the things which," etc. He says therefore "I send," etc., because "no one," etc., namely for your profit. Ps. 67:7: "who makes those of one manner to dwell in a house." "Who may be solicitous." Rom. 12:8: "he who is over others in solicitude." "With sincere affection," because it is only on account of God. 2 Cor. 1:17: "out of sincerity, as from God, before God, we speak in Christ." But the reason why "no one," etc., is because "all seek the things which," etc., that is, they do not seek the things which pertain to the salvation of neighbors and to the honor of God, but the things which pertain to gain and glory, and the things which are their own. But did not Luke and Epaphroditus and the others who were with the Apostle seek the things that were their own? I respond. It must be said that in the Apostle's company there were many who sought this, who also deserted him. 2 Tim. 4:10: "for Demas has forsaken me, loving this present world, and has gone to Thessalonica: Crescens to Galatia: Titus to Dalmatia: Luke alone is with me." But it is a custom that Scripture sometimes speaks of some as if of all. Jer. 6:13: "for from the least even to the greatest all are given to avarice, and from the prophet even to the priest all act deceitfully," etc. And so it is a fitting distribution. And if you wish to know how he conducts himself toward me, I respond, "the proof," etc., that is, as though he were a special son. 1 Cor. 4:17: "therefore I have sent to you Timothy, who is my dearest and faithful son in the Lord," etc. Him, therefore, so solicitous for you, so dear to me, I hope, etc. But why not at once? It should be known that it is otherwise with Christ than with the other saints. For in Christ is the fullness of graces, hence he always had knowledge of all things; not so the other saints. Hence the Apostle foresaw some things about the future concerning himself, and some things he did not know. And thus it had not been revealed to him whether he was to be freed from his chains. And therefore he says "soon," etc. Because if the opportunity is given, I will come in person. And therefore he says "I trust," etc. Yet nevertheless he was not freed from his chains. Ps. 17:29: "for you light my lamp, O Lord my God, enlighten my darkness." For there is always something dark in the saints. Then when he says "necessary," etc., he sets forth another of his disciples as an example, namely Epaphroditus. And first he describes him; second he shows how he should be received, at "receive," etc. Concerning the first he does two things: first he commends him; second he shows the cause of his sending, at "since indeed," etc.; third he explains it, at "for he was also sick," etc. He says therefore "necessary," etc. He calls him "brother," on account of faith. Matt. 23:8: "you are all brothers," etc. "Fellow-worker," namely in the labor of preaching. Prov. 18:19: "a brother who is helped by a brother is like a strong city." And "fellow-soldier," etc. Because they suffered tribulation together. 2 Tim. 2:3: "labor as a good soldier of Christ Jesus," etc. "Apostle," that is, teacher. This one was bishop of the Philippians, and was sent by them that he might serve the Apostle, and therefore he says "the minister of my need." Below, 4:18: "I am filled, having received from Epaphroditus, whom you sent, an odor of sweetness, an acceptable sacrifice, pleasing to God." But why? To satisfy the desire with which he desired to see you. Rom. 1:11: "for I desire you," etc. Likewise to relieve his own sorrow, because he was sorrowful over your sorrow, which you had conceived when you heard that he was sick. And he explains the cause, saying "for he was also sick even unto death," namely according to the judgment of the physicians, but not according to divine providence, but for the honor of God. John 11:4: "this sickness is not unto death, but for the glory of God." Therefore there follows, "but God had mercy on him." Ps. 6:3: "have mercy on me, O Lord, for I am weak," etc. "And not only," etc., because he had a temporal and natural sorrow over his afflictions, just as Christ also is read to have had at times. Consequently he concludes the sending, and the letter is clear, and he shows how he should be received, and second the reason for this. He is to be received honorably in the Lord, whose minister he is. Gal. 4:14: "you received me as an angel of God, as Christ Jesus." 1 Tim. 5:17: "the priests who preside well are to be held worthy of double honor: especially those who labor in word and doctrine," etc. And this "on account of," etc., that is, on account of God and the salvation of the faithful, "he approached even unto death." John 15:13: "no one has greater love, than that someone lay down his soul for his friends," etc. "Handing over." John 10:11: "the good shepherd lays down his soul for his sheep." And this "that he might fulfill," etc., what you personally were not able to do concerning service to me.”

“Holding forth the word of life,.... By which may be meant, either Christ the essential Word, in whom life was, and is, and who is called the quick or living Word, Joh 1:1; and here may be styled the Word of life, because he has all life in him; he has a divine life in him, as God, he is the living God; and it is given to him to have life in himself, as Mediator, for all his people; and he ever lives as man to make intercession for them: and because he is the author of life in every sense, of natural life to all men, of spiritual and eternal life to as many as the Father has given him: or else the Gospel is intended, and the doctrines of it; and which are sometimes called the words of eternal life, and of this life, Joh 6:68; and that because they are a means of quickening dead sinners, they are a savour of life unto life, Co2 2:16, and the Spirit that giveth life, and of enlivening and comforting living saints; they treat of Christ who is the life; by the Gospel, life and immortality are brought to light; that gives an account of everlasting life; points out Christ as the way to it, shows that meetness for it lies in regenerating grace, and a right unto it is in the righteousness of Christ. Now this Word of life is held forth, partly by the preaching of it to a dark world, as by some; and partly by professing it publicly, as it should be by all who are enlightened with it; and also by living lives and conversations becoming and suitable to it, That I may rejoice in the day of Christ. The apostle having observed the advantages that would accrue to themselves, and the benefit they might be of to the men of the world, by regarding the several exhortations he had given them, and which ends he mentions as reasons and arguments to enforce them, closes with taking notice of the use and service it would be to himself; it would give him joy and pleasure when Christ should come a second time to judge the world; and when dead in Christ would be raised, and set at his right hand, and these among the rest, to whom the apostle had been useful; and who continued to bear an honourable testimony in the world to Christ, and his Gospel, to the end: that I have not run in vain, nor laboured in vain; being blessed with such converts under his ministry, as were a credit to religion, an honour to the Gospel, and a crown of rejoicing to him. He expresses his ministerial function, and the discharge of it, by running in a race, as the ministry of a person is sometimes called his course, Act 13:25; in allusion to the Olympic games, which the apostle often refers to, when the conqueror obtained a crown; and it was enough for our apostle, and a crown of rejoicing to him, that his spiritual children walked in the truth, and as became it, to the end: and also by labour, and hard service, as the ministerial work is, when faithfully performed; and especially as his was, which was attended with so many difficulties, and yet with such constancy, diligence, and indefatigableness, all which was not in vain; and he could look back upon it with pleasure, when his followers stood fast in the faith, and adorned the doctrine of Christ.”

“Holding forth the word of life - An allusion, some think, to those towers which were built at the entrance of harbours, on which fires were kept during the night to direct ships into the port. Genuine Christians, by their holy lives and conversation, are the means of directing others, not only how to escape those dangers to which they are exposed on the tempestuous ocean of human life, but also of leading them into the haven of eternal safety and rest. That I have not run in vain - This appears to be a part of the same metaphor; and alludes to the case of a weather-beaten mariner who has been long tossed on a tempestuous sea, in hazy weather and dark nights, who has been obliged to run on different tacks, and labor intensely to keep his ship from foundering, but is at last, by the assistance of the luminous fire on the top of the tower, directed safely into port. Live so to glorify God and do good to men, that it shall appear that I have not run and labored in vain for your salvation.”

“Some, with Beza, conceive that there is an allusion to lights held forth as beacons to distressed mariners : but the term may signify simply : holding fast to the faith, which is the principle of salvation: "being of the number of those who shall be saved — having the seed of life, the pledge of life, life itself." St. Chrysostom.”

“Holding forth--to them, and so applying it (the common meaning of the Greek; perhaps here including also the other meaning, "holding fast"). The image of light-bearers or luminaries is carried on from Phi 2:15. As the heavenly luminaries' light is closely connected with the life of animals, so ye hold forth the light of Christ's "word" (received from me) which is the "life" of the Gentiles (Joh 1:4; Jo1 1:1, Jo1 1:5-7). Christ is "the Light of the world" (Joh 8:12); believers are only "light-bearers" reflecting His light. that I may rejoice in--literally, "with a view to (your being) a subject of rejoicing to me against the day of Christ" (Phi 4:1; Co2 1:14; Th1 2:19). that I have not run in vain--that it was not in vain that I labored for your spiritual good.”
