WhiteWings, Doc, and Paul have given you a lot of good information to think about. Thanks WhiteWings for posting all those scriptures... saved me from going to look them up.
If you really want to understand what we are here for and what the purpose of it all is, IMHO it seems to me there are a few concepts we need to wrap our heads around:
1. God is COMPLETELY 100% sovereign (not many people believe this even though they may say they do)
2. God will save everyone eventually (not many people believe this)
3. God is the creator of all, and is responsible for all. He works all according to his purposes - this includes evil. But his purposes are good - therefore he created evil for a good purpose.
Now the mainstream view makes a critical error in not fully believing in God's sovereignty. They would look at things more like this:
1. God is sovereign, except when it comes to our free choices to reject him and sin. Man's "sovereignty" actually overrides God's sovereignty.
2. Because man is sovereign, he is free to reject God, therefore hell must exist and God will not save all (even though it is God's will that all be saved - 1 Tim 2:4, 1 Tim 4:10, 2 Peter 3:9).
3. God created all... except all the evil stuff. That was created by Satan and ourselves.
Look at this way: Do you think God designed the biggest Windows program in the universe, and that Evil is some giant bug that slipped by his quality control? God made a mistake? I don't think so.
No, this all flies in the face of God being sovereign. Either he is sovereign or he isn't. The bible quite clearly says God is sovereign, in multiple hundreds of scriptures (just do a search on biblegateway.com yourself).
You seem to be worried about blaspheming God by attributing evil to Him. Yet you don't seem to be as worried about denying the full sovereignty of God - just something to think about - which some would say is the biggest blasphemy of all. If God is not sovereign, then He is not God.
Just because something is unpleasant or calamitous does not mean it is evil in the sense that a sadistic, torturing murderer is evil. If you chastise your child, it will not be pleasant for the child, but the end result will be 'good'.
I believe this to be an accurate view. God creates evil for a purpose - essentially for our own character growth. We are being pruned and refined until we will be ultimately good. And we can't be good until we know evil.
Either God does not lie or deceive, or He does. If the scriptures say both, then it's most likely a translation issue or not understanding all the factors, as the scriputures do agree and are not contradictory. I am being careful and at the end of the day, if my 'spirit' is uneasy in me, at the idea that God deliberately created Satan, to be 'evil', or deliberately set the scene to ensure that we suffered through 'evil' then I do have a problem reconciling that with the God you portray as loving EVERYONE, so much so that He will save everyone ultimately. I have only come across this idea of evil being 'God's fault' via UR. This makes me somewhat suspicious of UR. It's as if you are presenting two extremes. Bear in mind I come from a more 'orthodox' view of God etc, and I've always had a problem with evil, but what you are proposing seems crazy and blasphemous (even if you sincerely believe yourselves to be right on this matter).
You are correct that the scriptures never contradict - only our understanding seems to contradict.
Whitewings was right on here. Your logic seems to fail at this point. How is UR more extreme than the mainstream? The mainstream says God loves everyone but will consign 90% of humanity to eternal torment. UR says God loves all and will save all, but along the way (like any good parent) He is going to teach us some stuff. Sometimes it won't be fun, but ultimately its for our own good.
Do you think God is just putting us through all these evil situations for fun? Or is it for some greater purpose that requires an experience of evil?
Have you ever thought why didn't He create everyone "good" to begin with? Why did He even allow evil at all? He is sovereign right? Why not just create us in heaven and everyone would be happy? Why did he create Satan? Why does he "allow" evil?
The reason is: He is creating us to be good! RIGHT NOW - it is a process. He is still making us. We are being formed as we speak. We are learning knowledge of good and evil, and eventually we will be shown how to be ultimately good. God didn't make (past tense) us in his image. No. He is (present and future tense) still making us in his image. This life we are in is just part of the process that will carry on through the ages until God is all in all.
If you are right, then it is up to God to show me. I want to know the truth. I believe in my 'spirit' that you are wrong on this matter.
It is up to God to show you. What you can do is pray that He give you understanding. Be careful though, you don't always get the answer you want. That's what happened to me...
