Romans 5:12–17
Therefore, just as sin entered the world through one man, and death through sin, so also death was passed on to all men, because all sinned. / For sin was in the world before the law was given; but sin is not taken into account when there is no law. / Nevertheless, death reigned from Adam until Moses, even over those who did not sin in the way that Adam transgressed. He is a pattern of the One to come.
Romans 6:23
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
