I think it's sad and degrading to Christianity that we have those who believe if God predestines a person, yes, even a believer, to abuse children, they will gladly do it for God. If it doesn't pull your heartstrings, then something is definitely wrong.
Nor is He faithful to His Word.
What is the most important to you - God's sovereignty or His word? You have both of them fighting against each other.
Arcoe, a few observations from my end
For starters, The Bible is clear that God created everything for its purpose, even the wicked. Prov 16:4
It seems to me that we can derive an important, comforting truth from the fact that evil has a purpose in God's overall plan.
If evil has no purpose, that makes it arbitrary and meaningless. If evil has no purpose, why does God allow it? Or is God powerless to stop it? If evil has no purpose, but is arbitrary, and God has the power to stop it, yet doesn't, that means He himself is arbitrary. If he doesn't have the power to stop it, then God ceases to be God.
Therefore the only alternative is that evil has a purpose. Who's purpose? God's purpose. In God's infinite wisdom he determined that He would be best glorified by his creation if evil existed and had a purpose.
For example, even promises to believers are predicated on evil existing: "All things work together for the good of those who love God". Surely evil is part of those all things. Therefore, evil existing is important for the eventual betterment of believers.
If evil has no purpose, that means those horrible examples you keep using such as child abuse and rape are arbitrarily running rampant in the universe and either God 1) is powerless to stop them or 2) arbitrarily allows them, for no reason whatsoever. He has no purpose for them, but continues to allow them. What does that say bout him?
However, if evil things have a purpose, then we can trust that God is wise and knows what He is doing. His purpose, though hard, can be trusted, and we can find comfort in Him.
Imagine your wife got raped. Who would you turn to for comfort? If, in your worldview, that rape had no purpose, then why would you turn to God to seek understanding and comfort? For in such a view, God arbitrarily let it happen or was powerless to stop it, both disqualify him as a source of understanding and comfort.
However, I submit to you that we can turn to God precisely because His plan can be trusted and he has a reason for all things, and therefore we can come to him when we need comfort and understanding.
The rub is this: If you believe God has a purpose for evil, you can consistently turn to him in hard times.
If you don't, then you cannot consistently turn to him in hard times.
Fact: all Christians turn to God in hard times
Logical conclusion: deep down we know that God is soveriegn, even over the hard times. He is not arbitrary, but has a purpose, thus we can turn to him for understanding. Therefore, he is not powerless to stop it.
So Arcoe, which universe would you rather live in?
1) A universe where evil has no purpose, but is arbitrary which makes God arbitrary or powerless
2) a universe where evil has a purpose
Which is more comforting to you? To me, #1 is a horrifying thought.
