6 For when we were yet without strength, in due time in due time: or, according to the time Christ died for the ungodly.
English Standard Version
6 For while we were still weak, at the right time Christ died for the ungodly.
6 Christ arrives right on time to make this happen. He didn't, and doesn't, wait for us to get ready. He presented himself for this sacrificial death when we were far too weak and rebellious to do anything to get ourselves ready. And even if we hadn't been so weak, we wouldn't have known what to do anyway.
New King James Version
6 For when we were still without strength, in due time Christ died for the ungodly.
New Living Translation
6 When we were utterly helpless, Christ came at just the right time and died for us sinners.
Christ died for sinners; not only such as were useless, but such as were guilty and hateful; such that their everlasting destruction would be to the glory of God's justice. Christ died to save us, not in our sins, but from our sins; and we were yet sinners when he died for us. Nay, the carnal mind is not only an enemy to God, but enmity itself, Zechariah 11:8. And that for such as these Christ should die, is a mystery; no other such an instance of love is known, so that it may well be the employment of eternity to adore and wonder at it. Again; what idea had the apostle when he supposed the case of some one dying for a righteous man? And yet he only put it as a thing that might be. Was it not the undergoing this suffering, that the person intended to be benefitted might be released therefrom? But from what are believers in Christ released by his death? Not from bodily death; for that they all do and must endure. The evil, from which the deliverance could be effected only in this astonishing manner, must be more dreadful than natural death. There is no evil, to which the argument can be applied, except that which the apostle actually affirms, sin, and wrath, the punishment of sin, determined by the unerring justice of God. And if, by Divine grace, they were thus brought to repent, and to believe in Christ, and thus were justified by the price of his bloodshedding, and by faith in that atonement, much more through Him who died for them and rose again, would they be kept from falling under the power of sin and Satan, or departing finally from him. The living Lord of all, will complete the purpose of his dying love, by saving all true believers to the uttermost. Having such a pledge of salvation in the love of God through Christ, the apostle declared that believers not only rejoiced in the hope of heaven, and even in their tribulations for Christ's sake, but they gloried in God also, as their unchangeable Friend and all-sufficient Portion, through Christ only.
