6:23 {11} For the wages of sin [is] death; but the gift of God [is] eternal life through Jesus Christ our Lord.
(11) Death is the punishment due to sin, but we are sanctified freely, to everlasting life.
6:23 The wages of sin [is] death, one of the saddest, but profoundest truths of the world. Sin is a master of his servant and pays wages.
But the gift of God [is] eternal life. God gives to those who turn from sin, life eternal. It is his gracious gift, conditioned on refusing to be the servant of sin longer, and is through Jesus Christ our Lord.
6:23 Death - Temporal, spiritual, and eternal. Is the due wages of sin; but eternal life is the gift of God - The difference is remarkable. Evil works merit the reward they receive: good works do not. The former demand wages: the latter accept a free gift.
6:21-23 The pleasure and profit of sin do not deserve to be called fruit. Sinners are but ploughing iniquity, sowing vanity, and reaping the same. Shame came into the world with sin, and is still the certain effect of it. The end of sin is death. Though the way may seem pleasant and inviting, yet it will be bitterness in the latter end. From this condemnation the believer is set at liberty, when made free from sin. If the fruit is unto holiness, if there is an active principle of true and growing grace, the end will be everlasting life; a very happy end! Though the way is up-hill, though it is narrow, thorny, and beset, yet everlasting life at the end of it is sure. The gift of God is eternal life. And this gift is through Jesus Christ our Lord. Christ purchased it, prepared it, prepares us for it, preserves us to it; he is the All in all in our salvation.
