There are no innocents.
Romans 3:10-11.
Romans 3:23.
Ecclesiastes 7:20.
So what is your answer to the op? Is it your understanding that sin is a state of being rather than an act in spite of the definitions and descriptions of sin I have already posted in one of my comments? Is it your position that those three passages you referenced somehow modifies those definitions?
If you were the apostle Paul writing to the Romans in 58 AD (the year he wrote the epistle to the Romans) and you were looking back over a clearly defined time period, the time between Adam and Moses, which was over 1500 years past, would you not realize that you were not addressing a single child or fetus in the womb, but all who have grown up, sinned and died, thus proving your point that in Adam all die even before the written law was given defining sin and even though sin was not imputed to them in the absence of law?
12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
13 (For until the law sin was in the world: but sin is not imputed when there is no law.
14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam’s transgression, who is the figure of him that was to come.
Do you not see his point? None of those people were guilty of Adam's sin, nevertheless sin and the resulting death was introduced into the world through Adam and none had the power in their flesh to resist sin, all violating their consciousness of right and wrong by their deeds and all having sinned and died.
Now Adam is given as a figure of Jesus Christ in Paul's present tense. He came to give the power over sin, the gift of God, the Spirit, who we learn is life and it was for as many as were affected by Adam. So in Adam sin and death to the world. In Christ imputed righteousness and life to the world. See the remainder of this parenthetical statement by the great apostle.
15 But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift (t
he gift is the Spirit of Christ making the recipient a three part man, a trinity and in the image of Christ) by grace, which is by one man, Jesus Christ, hath abounded unto many.
16 And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification.
17 For if by one man’s offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ)
18 Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
19 For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous.
20 Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound:
21 That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
These are simple words. I do not know what makes them so hard for people to grasp.
2Co 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
