There's an excellent point made about omniscience and omnipotence. I wish I could credit the source, but honestly, I forgot. I believe it was a Greek philosopher, but I can't say for certain. If someone knows, I would appreciate knowing who to attribute this to.
At any rate, to be omniscient and omnipotent is to be responsible for every action anyone ever makes. Put it simply, if you can know everything and do anything, then by performing any action at all, you know exactly what the ramifications are from execution until eternity.
Let's put this into context. God not only performed an action, He set up the
entire scenario that Adam found himself in. God, being omniscient, would know, then, the result of the actions that He, Himself, took leading up to the fall. Who's to say that the modification, omission, or addition of any slight detail would have resulted in a completely different outcome? In a word: God. God, with His infinite wisdom and knowledge, knew every scenario possible and had the capability of setting any one of them into motion. Therefore, even before Adam fell, He not only knew what would happen to Adam, He also knew that He would be sending the vast majority of humanity to suffer eternally because of it.
If we are to believe that God and His will is perfect and that this will is to save all of humanity, as is evidenced in 2 Timothy, then how could one account for the sheer imperfectness of a plan that involves so much loss? In practical terms, perfection is that which is a 1:0 ratio of gain to loss. What we see with God, at least in His desire to save souls, is a ratio that is heavily weighted towards loss.
Even if you ignore the notion that God is directly responsible for the result of a scenario that He set up, knowing full well what would happen, then how do you explain the sheer imperfection of God's plan? Are you honestly suggesting that it is beyond God's capability and wisdom to implement a plan that flawlessly incorporates salvation and free will?
Supposing that free will is fundamentally important to this plan, why not make the choice more abundantly clear? A person makes obvious choices in life all the time; choosing to use bleach to clean a bathtub instead of drinking it, for example. While the example is not perfect, it is scalable. Seemingly "no-brainer" decisions are still a matter of free-choice. An option that is infinitely more beneficial and attractive than any alternative doesn't eliminate free will.
In this vein, we're to believe that God is not sufficiently capable of rationalizing a situation by which every human being who has ever existed is given a clear and reasonable choice in the matter of salvation. Even many Christians, in their evangelizing, try to boil the situation down to going to hell or living for eternity in bliss. If such is the case, why can't this be made more obvious to everyone?
Instead, we have a plan by which people suffer and die, only to go to hell because they were not provided sufficient evidence, or any at all, to save them from their fate. You can blame them for their decisions, or you can blame the being that put them into that situation to begin with, knowing full well how the scenario would play out. Or, even still, you can live life simply appreciating everything for what it is and knowing that, at the end of your time here on earth, that it was good enough.
After evaluating this scenario several years ago and struggling with the idea that God was either evil, incompetent, or some combination of the two, I finally came to the latter conclusion. It has been the healthiest and most liberating decision of my life.
