Setting aside the question of why we are not absolutely perfect beings, and shifting to the more applicably practical question of faith and trust in the one right Person in all of reality having the qualifications and character to be God, a good place to start is the biblical account of the calling and mission-plan of the apostle Paul.
After his road to Damascus experience, Saul/Paul could have said to Jesus that yes, he had been entirely wrong and mistaken about persecuting the early Christian church, but that he was too offended that God had allowed him to go this far in error, to then step into this new mission-calling to preach Jesus as the risen Christ.
After his exceptional education in Jerusalem under the acclaimed teacher Gamaliel, Saul/Paul could have complained to Jesus that God the Father should have told him earlier about looking both ways before crossing the street, before being allowed to proceed in ignorance to create so much havoc in attacking the Christian church in Jerusalem.
Saul/Paul could have reasonably responded to the new calling of Jesus to go out into the larger sphere of the Greco-Roman world to preach the gospel truth of a risen Christ, that he was both too mad at God and at the same time totally unable to forgive himself for being ignorant about the preeminence of faith in the biblical narrative stories, and within the proper context of the Law of Moses in Judaism.
Saul/Paul could have justifiably complained that God should have given him the needed discernment upfront to be able to recognize Jesus of Nazareth as the Christ, without the extreme measure after-the-fact of a revelation by way of a blinding light on the road to Damascus, to learn this truth the hard-way.
But this reveals possibly the whole point God is making in the creation of this physical universe, that in the Garden of Eden we were unable to parse the malicious half-truth that eating a piece of fruit from a specific tree would render us into autonomous, self-sufficient gods having the knowledge of good and evil.
God did not rescue us at that critical juncture because non-divine, free-thinking beings lacking timeless foresight are susceptible to the persuasively clever arguments delivered by a charismatic, outwardly beautiful liar…and this particular truth has to be demonstrated over time through human history in a variety of laboratory-type, empirically investigated lessons-learned.
Whether it is Adolf Hitler, Benito Mussolini, Joseph Stalin, Jim Jones of Jonestown, Guyana, or Satan in the holographic guise of a beautiful talking serpent, in the vast eternity of reality some of the moral concepts within the knowledge of good and evil are difficult to nail-down without the benefit of first-hand field research.
The divine brilliance revealed in the method of the calling of Saul/Paul through the road to Damascus experience, was that God was able to flip Saul into Paul the apostle in a moment of time, creating in an instant an exceptionally qualified rabbinical Pharisee yet having the super-humility to engage with the Gentiles on their level without looking derisively down his nose at their ignorance about God.
Without Saul/Paul’s colossal blunder in persecuting the early Christian church in Jerusalem, within the environment of a world having evil and suffering, there is no Paul the apostle to the Gentiles, and no Paul a new creature in Christ beloved widely in the early Christian churches he was instrumental in founding, as revealed in Romans 16.
This conversion story of Paul the apostle displays at the very heart of the matter our deep need for Jesus Christ to be “the way, the truth, and the life” in our lives, to approach the deepest meanings in the broad array of moral concepts at the outer edge of their end-points of understanding.
We need this broken world with all of its evil and suffering, for exceptional goodness and brilliant virtue to immerge.
This is epitomized in the cross and the resurrection of Jesus that inaugurates at the highest imaginable level God sacrificing Himself, so that we can repent and embark on a guided research program into the knowledge of good and evil, through the lens of a fallen yet redeemed, imperfect moral character.
Even Peter has difficulty with discernment as he tries to figure-out his right course of action at the night trial of Jesus (Mt. 26:34-35, 69-75).
