He spoke in parables because He knew people are stupid and it would take God unvealing the message behind the parables in their hearts before they would ever be able to understand.
He came for the sole purpose of paying the sin debt of humanity through His substitutional death. That sounds like He wanted to save it to me.
God doesn't have to blame you for the sins of your fathers. He's blaming you for YOUR sins.
He didn't create mankind imperfect. It became imperfect of its own free will. How does He bear fault for Adam's actions? He told Adam not to do what he did.
You are condemned to hell because you have broken God's law and hated Him in your heart. He became a man a died for you so that you could be reconciled to Him if you would only accept what He did as payment for your debt. He doesn't send you to hell; you do that yourself by rejecting Him. But it is entirely up to you where you end up. He has made a way of salvation through Jesus.
God had no beginning and He will have no end. He is eternal. You will never be able to grasp this. It is beyond your capacity as a human to even wrap your mind around what God is. Ultimately...if you could even imagine His greatness, He wouldn't be that awesome a God, now would He? When you think about it, it is quite logical that you, the creation, fail the understand the work of the Creator.
