God doesn't tempt us. You're right. But he does give us obstacles to TEST us. I read a scripture about this and I can't seem to remember it. It used the word "tempt," but then I looked it up in other bibles and the word "tempt" meant "test." God does put us through tests so that He can see if we will listen to Him or not. Even though He knows what's in the future and what we're going to do, he wants us to learn!
Okay, I found the scripture, "And it came to pass after these things, that God did tempt Abraham, and said unto him, Abraham: and he said, Behold, here I am." -Genesis 22:1 [KJV]
But you just have to look into the context. The word "tempt" means to "test". It's not that God is TEMPTING us to sin. But instead, he's TESTING us.
