Romans 5:12-14 “Therefore, just as through one person sin entered the world, and through sin, death, and thus death came to all, inasmuch as all sinned - for up to the time of the law, sin was in the world, though sin is not accounted when there is no law. But death reigned from Adam to Moses, even over those who did not sin after the pattern of the trespass of Adam, who is the type of the one who was to come.” Romans 5:18-21 “In conclusion, just as through one transgression condemnation came upon all, so through one righteous act acquittal and life came to all. For just as through the disobedience of one person the many were made sinners, so through the obedience of one the many will be made righteous. The law entered in so that transgression might increase but, where sin increased, grace overflowed all the more, so that, as sin reigned in death, grace also might reign through justification for eternal life through Jesus Christ our Lord.” Exodus 34:5-7 “The Lord came down in a cloud and stood with him there and proclaimed the name, “Lord.” So the Lord passed before him and proclaimed: The Lord, the Lord, a God gracious and merciful, slow to anger and abounding in love and fidelity,[b] continuing his love for a thousand generations, and forgiving wickedness, rebellion, and sin; yet not declaring the guilty guiltless, but bringing punishment for their parents’ wickedness on children and children’s children to the third and fourth generation!” Psalm 51:5-7 “my sin is always before me . . . Behold I was born in guilt, in sin my mother conceived me.” Sirach 25:33 “From the woman came the beginning of sin, and by her we all die.”
