How can I put my carnal feelings aside?

From the book The Fall of Man and the Perfect Salvation, I just learned that all of my thoughts are evil and ever thing that I think and feel can get in my way of believing in Gods Word, and it is. Its the only thing that stoping me. I also learned that this is the Truth of God and it will set me free. Instead of me rejoicing in the Truth, I got scared because I know that what I think and feel is getting in the way. I feel crushed. How can I ecsape these evil thoughts and feeling, so that I could believe in the water and the Gospel of the Spirit? The book saysIf we insist on keeping own emotions, our own stubbornness, or our own thoughts, then we can never become God’s children. How can I put aside all my emotions, stubborness, and thoughts? I want to be able to have more faith. I want to really believe what Jesus did for me and everyone else, but the things that I think and feel are getting the way.
