Reading through the Bible from the very beginning, you will see that there is one consistent theme, and that is God's great love and compassion towards us. He is unchangeable, and in this we can have great confidence. It seems there is no greater motivation for faith than knowing this, God is absolutely for us. He wants us to succeed. It makes it easier to have confidence in fulfilling our purpose and destiny here on the Earth when we know that He has called us and ordained for us to succeed.
