Rom 5:8

“By saying that Christ died for us while we were yet sinners, Paul gives us hope that we will be saved through him, much more so now that we are cleansed from sin and justified against the wrath which remains for sinners. The One who so loved his enemies that he gave his only Son to die for us will surely be much readier to grant those who have received this gift and been reconciled to him the further gift of eternal life.”

“Moreover, we do not prejudge when the Lord is to be the judge; save that if He shall find the repentance of the sinners full and sound, He will then ratify what shall have been here determined by us. If, however, any one should delude us with the pretence of repentance, God, who is not mocked, and who looks into man's heart, will judge of those things which we have imperfectly looked into, and the Lord will amend the sentence of His servants; while yet, dearest brother, we ought to remember that it is written, "A brother that helpeth a brother shall be exalted; " and that the apostle also has said, "Let all of you severally have regard to yourselves, lest ye also be tempted. Bear ye one another's burdens, and so fulfil the law of Christ; " also that, rebuking the haughty, and breaking down their arrogance, he says in his epistle, "Let him that thinketh he standeth, take heed lest he fall; " and in another place he says, "Who art thou that judgest another man's servant? To his own master he standeth or falleth; yea, he shall stand, for God is able to make him stand." John also proves that Jesus Christ the Lord is our Advocate and Intercessor for our sins, saying, "My little children, these things write I unto you, that ye sin not. And if any man sin, we have an Advocate with the Father, Jesus Christ the Supporter: and He is the propitiation for our sins." And Paul also, the apostle, in his epistle, has written, "If, while we were yet sinners, Christ died for us; much more, being now justified by His blood, we shall be saved from wrath through Him."”

“God becomes the object of love when he conveys how much he loves us. For when someone does something without obligation, one demonstrates love in a special way. And what would be less of an obligation than that a master who is without sin should die for his faithless servants, and that the Creator of the universe should be hanged for the sake of his own creatures? Note that when the apostle says that believers in Christ were once sinners he means that now they are no longer sinners, so that they may recall how they ought to behave.”

“Then when he says, but God commends, he responds to the foregoing question. First, he sets out his response; Second, he argues from this to what he intends, at much more; Third, he shows how this follows of necessity, at for if, when we were enemies. He says therefore first: it was asked why Christ died for the ungodly, and the response to this is that, through this, God commends his charity towards us, i.e., through this he shows that he loves us to the greatest degree, because if when as yet we were sinners . . . Christ died for us, and this according to the time, as was explained above. The very death of Christ shows God's love for us, because he gave his own son that he should die in making satisfaction for us: for God so loved the world that he gave his only Son (John 3:16). And so as the love of God the Father for us is shown by the fact that he gives his own Spirit to us, as was said above, so also it is shown by the fact that he gave his Son, as is said here. But by the fact that he says, commends, he indicates a certain immensity of the divine love, which is shown both by his own deed, because he gave his Son, and by our condition, because he was not moved to do this by our merits, since we were still sinners: God who is rich in mercy, on account of the exceedingly great love wherewith he has loved us, while we were still dead in sins, has raised us to life with Christ (Eph 2:4).”
