Ah, so maybe you can give the answer: When Adam, the "living soul" (living because God's life, or grace, had been "breathed" into him) was in the Paradise of Eden, and not fallen, and not dead in sin, not having committed any sin yet, by what means did he choose to eat of the fruit of the tree of the knowledge of good and evil, and to succeed in eating it?
Adam's imperfect nature, because he is a creature, allowed him to be tempted and sin.
After the fall man cannot choose freely, sin has impact him through Adam and the so called freewill of the creature is constrained.
Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again. (Joh 3:5-7)
Christ explains “that which is born of flesh is flesh.” The flesh can do nothing spiritual.
All humanity was in Adam covenantally.
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: (Rom 5:12)
Notice that “by nature,” that is in our nature (“flesh is flesh”) state we were “children of wrath.” We were in a sinful state and fulfilled our own “desires of the flesh.”
And you hath he quickened, who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. (Eph 2:1-3)
And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; (Col 2:13)
God does the “quickening” or makes us alive, the actions of God are not subject to the creature, for He is all knowing and all powerful.
All of this was in God's plan from eternity.
GOD PREDETERMINED THE FALL OF ADAM; this fell under his decree, as all things do that come to pass in the world; there is nothing comes to pass without his determining will,
“Who is he that saith, and it cometh to pass, when the Lord commandeth it not?” (Lam. 3:37), nothing is done, or can be done, God not willing it should be done: that the fall of Adam was by the determinate counsel and foreknowledge of God is certain; because the sufferings and death of Christ, by which is the redemption of men from that sin, and all others, were ordained before the foundation of the world; and which must have been precarious and uncertain, if Adam’s fall was not by a like decree (Acts 2:23; 4:28; 1 Pet. 1:20), but then neither the foreknowledge of God, nor any decree of God, laid Adam under a necessity of sinning; it is true, there arises from hence a necessity of immutability, that is, that the things God has decreed should unchangeably come to pass, but not a necessity of co-action or force; as Judas and the Jews sinned freely, the one in betraying, the other in putting Christ to death; so Adam sinned freely, without force or compulsion, notwithstanding any decree of God concerning him; so that these do not make God at all chargeable with being the author of his sin; he and he alone was the author of it. - John Gill
