Inevitability.
That which unavoidably comes to pass. Not merely predictable but certain.
In the mind of God, I am quite sure, that is what the fall of a creature like man, made in God's image with its consequent independence and freedom, would have been considered.
Line up a thousand people and test the premise and all one thousand would prove it true, as would a million, or billions, or whatever number might be selected. You see, it is impossible for that which is not God to replicate the free choice and will of him who is. If God could be replicated by that which isn't him, then God wouldn't be God. The very thing that grants the freedom to choose determines that choice will, without fail, deviate from God's and become sin.
Is there anything that God doesn't know about a course of action he intends to take? If he is omniscient, certainly there isn't. Since he is, God would need no more than one generic sample of a thing made along the line of a human in order to demonstrate by test the nature of this glitch to any and all observers (including that human in the test). One would be more than sufficient-- as that one went, so any others would go. The prototype is all that is necessary to make the proof that then would apply to all others.
Adam was that sample, the prototypical temporal man. Eve was as well since "male and female he created them." Adam/Eve was not God, merely the image of God, and ignorant (innocent) rather than aware and knowing. They were created to do as they pleased, like God, but with one exception: they were not to eat from the tree of the knowledge of good and evil. One pair of both models, one rule impinging upon their freedom was more than adequate to demonstrate that inevitable glitch that would manifest in all others of the type given the chance.
The prototype test in Eden proved to all creation that a human made in the image of God would rely on his or her own judgment rather than trust in the judgment of God. That is the particular choice from which deviation, any and all deviation, from God's will comes from. Had they trusted God there was nothing to hinder them from eating of the tree of life and living eternally. They didn't, demonstrated the inevitable glitch of which we speak and brought all of creation down with them into sin and death.
They trusted themselves, trusted the Serpent, but they did not trust God. Thereby, they became disqualified and unsuitable for an eternal life walking in the freedom intrinsic to the image of God.
Jesus was the prototypical eternal man. Not only was he flesh and bone and soulish in a human sense, he was also God in the flesh. Tested though he was, he stayed true to the Heavenly Father. He trusted his Father's judgment and stayed dedicated to his will. He never deviated, not even once from his Heavenly Father's will though he had at every turn the freedom to do so. He demonstrated that God dwelling in unity within the soul and frame of a human being made in his image was a sufficient synthesization to achieve perfection in being and eternal life.
Those who are in Christ and in whom is Christ have become, in earnest, the kind of human Christ is. We were in Adam and did as Adam did. We were flawed and not capable of being truly righteous. By faith in Jesus and rebirth in the Spirit of God we are in Jesus and Jesus is in us. What he did, as he did, we also will do. As he is righteous so are we. He lives forever and so will we.
We were Adam, and never were nor could we ever be righteous. Now we are Christ, and will be perfectly so hereafter, and as such, will always be righteous throughout all eternity. What we never were, nor could ever be, we will be always.
