he does... but, well it's complicated even to the most knowledged christians
however i will try to explain...
our sin 'seperates' us from God
and God is so pure that he cannot touch it... just to help you understand we'll say it 'burns' him so much (Moses wants to see God, but because Moses is a sinner, God says no you can't see my face, but he loves Moses and wants to be with Moses so he lets Moses see his back, and just to get an idea of how pure God is, Moses was so radient that the people of Isreal couldn't even look at moses in the face anymore, because it was too bright, he had to wear a vail
but go loved us so much that he sent his only son to die on the cross and save us from our sins (John 3:16) so we could be close to god
the reason he can't just save us is because many people don't belive in him, and he needs us to help bring them to christ
also, God is angry at us when he gives us chance after chance to come to him, and we don't... 'the wrath of God is being revealed from heaven against alll the godlessness and wickedness of men who surpress the truth about their wickedness (they don't admit they sin) since what may be known about God is plain to them, because God has made it plain to them (he's revealed himself to them and they won't accept him as their savior and lord)
