So why do we make wrong choices? Once we answer that question, we will be in a good position to address Adam's sin
We make wrong choices because we have free will. Not because we are sinners, nor have a sin nature. Adam did not have a sin nature, nor was Adam a sinner. Adam did not sin. Adam disobeyed God. At the moment Adam disobeyed God, Adam died physically and spiritually. Adam received a corruptible body of flesh, that now had a sin nature which was full of lust and the desire to please only the body of flesh and blood.
Romans 5:9-14
9 Therefore, since we have now come to be considered righteous by means of his bloody sacrificial death, how much more will we be delivered through him from the anger of God’s judgment!
10 For if we were reconciled with God through his Son’s death when we were enemies, how much more will we be delivered by his life, now that we are reconciled!
11 And not only will we be delivered in the future, but we are boasting about God right now, because he has acted through our Lord Yeshua the Messiah, through whom we have already received that reconciliation.
12 Here is how it works: it was through one individual that sin entered the world, and through sin, death; and in this way death passed through to the whole human race, inasmuch as everyone sinned.
13 Sin was indeed present in the world before
Torah was given, but sin is not counted as such when there is no
Torah.
14 Nevertheless death ruled from Adam until Moshe, even over those whose sinning was not exactly like Adam’s violation of a direct command. In this, Adam prefigured the one who was to come.
Our sin is not exactly like Adam's violation of a direct command. Adam disobeyed God. Adam was not a sinner, nor had a sin nature. Jesus Christ was the Second Adam. His obedience on the Cross was God Himself being obedient to restore the one command Adam disobeyed.
Romans 5:15-21
15 But the free gift is not like the offence. For if, because of one man’s offence, many died, then how much more has God’s grace, that is, the gracious gift of one man, Yeshua the Messiah, overflowed to many!
16 No, the free gift is not like what resulted from one man’s sinning; for from one sinner came judgment that brought condemnation; but the free gift came after many offences and brought acquittal.
17 For if, because of the offence of one man, death ruled through that one man; how much more will those receiving the overflowing grace, that is, the gift of being considered righteous, rule in life through the one man Yeshua the Messiah!
18 In other words, just as it was through one offence that all people came under condemnation, so also it is through one righteous act that all people come to be considered righteous.
19 For just as through the disobedience of the one man, many were made sinners, so also through the obedience of the other man, many will be made righteous.
20 And the
Torah came into the picture so that the offence would proliferate; but where sin proliferated, grace proliferated even more.
21 All this happened so that just as sin ruled by means of death, so also grace might rule through causing people to be considered righteous, so that they might have eternal life, through Yeshua the Messiah, our Lord.
