“"If the Lord," he saith, "had not helped me: within a little my soul had dwelt in hell" (ver. 17). I had almost plunged into that pit which is preparing for sinners: that is, my soul had dwelt in hell. Because he already began to waver, and nearly to consent, he looked back unto the Lord. Suppose, for example's sake, he was insulted to tempt him to iniquity. For sometimes the wicked flock together, and insult the good; especially if they are more in number, and if they have taken him alone, as there is often much chaff about one grain of wheat (though there will not be when the heap hath been fanned); he is then taken among many wicked ones, is insulted, and surrounded; they wish to place themselves over him, they torment him and insult him for his very righteousness. A great Apostle! say they; Thou hast flown into heaven, as Elias did! Men do these things, so that sometime, when he listeneth to the tongue of men, he is ashamed to be good among the wicked. Let him therefore resist the evil; but not of his own strength, lest he become proud, and when he wishes to escape the proud, himself increase their number. ...”

“But why is there no fear of uttering an indirect lie? We do not deny that free will is healed by the grace of God, but we believe that we make progress through the daily grace of God, and we trust in its help. And people say, "It is in my own power to do good." If only people did do good! O empty boasting of wretchedness! Every day they disclaim sin, and in their boasting they attribute to themselves unaided free will, not scrutinizing their conscience, which cannot be healed but by grace, so as to say, "Be merciful to me, heal my soul, for I have sinned against you." What would those do who boast of their own free will—which is not denied so long as it is helped by the grace of God—if death had now been swallowed up in victory, if our mortal were putting on immortality and our corruptible were putting on incorruption? Behold, their wounds fester, and they seek a remedy in pride. They do not say with the just person, "Unless the Lord had been my helper, my soul had almost dwelled in hell." They do not say with the saint, "Except the Lord guards the city, he watches in vain that guards it."”

“Unless the Lord had been my help,.... Against her enemies, which were so many and mighty, and her friends so few and feeble, and having no heart to defend her cause; especially this will be the case at the time of the slaying of the witnesses; but the Lord will appear, and help her; the Spirit of life, from him, shall enter into them, and cause them to live again, and to ascend up to heaven; and shall destroy great numbers of their enemies, and the rest shall be frightened, and give glory to God, Rev 11:11, my soul had almost dwelt in silence; or "within a little", or "must quickly" (e); not only have been, but must have dwelt, continued in silence, in the grave; see Psa 115:17 his case being desperate, like that of the apostles, when they had the sentence of death within themselves, Co2 1:10, this is to be understood not of the soul precisely, and abstractly considered, which dies not, nor is it silent after death; but of the whole person, being a part for the whole; and of the person, with respect to the mortal part, the body, which only dies, and while in a state of separation, or in the grave, is silent, and ceases from all operations of life: perhaps this may have some respect to the silencing of the witnesses, which is a principal thing meant by the slaying of them; a stop put to their ministrations, partly by the edicts of their enemies, and partly by the discouragement of their friends, their shyness, and negligence of them; and which silence will be almost total, if not altogether; though it will last but for a short time; they shall not dwell or continue in silence, but will open their mouths again; signified by the angel flying through the midst of heaven, with the everlasting Gospel, Rev 14:6. (e) "quasi parum", Montanus, Gejerus, Junius & Tremellius, Piscator.”
