I'm sure he is not 100% pleased with me and the way I live but I can only do so much in this skin. I have many ingrained desires and wants which, without supernatural help, I cannot overcome.
I think this statement is key in knowing why you haven't come to understand who Christ is. Jesus said, "My doctrine is not mine, but his that sent me. If any will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself (John 7:16-17)."
The key in knowing if Jesus is from God, is, according to Jesus, to follow Jesus' doctrine/teachings. It sounds like a challenge to me. In the sense that Jesus is challenging us to find out whether or not He is from the one true God, or if he speaks of himself. The Jews of His time wanting to know the same question you are asking yourself, and this is the answer Jesus gave.
I quoted your paragraph above because this is what you need to let go of if you want to find Jesus. You must let go of the idea that you can't change, unless God intervenes. Many people use this same argument as an excuse for their lack of obedience to Him. Sure, we may not be perfect or get it right... But the question is: Are we trying to change? We know within ourselves that we can change for something we
really want, so we know we are capable of changing... The question remains: Do we really want to change those sins that are in our lives, or do we want to continue in it? God comes into the picture
after we make the decision to change. God gave us free will for a reason. He will step in when we allow Him too, and He won't step in if we keep ourselves closed. It's as simple as that.
The more we try to put Jesus' teachings into action, the more Jesus will become revealed in our lives as a
living spirit.
In peace
