48 As was the man of dust, so it is with those who are of dust: and as is the man of heaven, so it is with those who are of heaven.

John 3:6
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Romans 5:12-21
12 Therefore, since through one man sin entered into the world, and death by sin; so death spread to all men, for all have sinned:
13 For though sin was in the world before the law: sin is not taken into account when there is no law.
14 Nevertheless death reigned from Adam to Moses, even over those who had not sinned in the same way as Adam, who is the pattern of him who was to come.
15 But the free gift is not like the offence. For if through the offence of the one many died, how much more did the grace of God, and the gift that came by the grace of the one man, Jesus Christ, overflow to many.
16 And the effect of the gift is not like the effect of the one who sinned, judgment following one trespass and resulting in condemnation; but the free gift came following many offences and resulted in justification.
17 For if by one man's offence death reigned through that one; much more shall those who receive abundance of grace and the gift of righteousness reign in life through the one, Jesus Christ.
18 Therefore, as the offence of one brought judgment upon all men, resulting in condemnation; even so by the righteousness of one came justification that brings life for all men.
19 For just as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
20 The law entered, that offences might increase. But where sin increased, grace increased all the more:
21 So that as sin has reigned in death, even so might grace reign through righteousness to bring eternal life through Jesus Christ our Lord.
