And the law is not of faith: but, The man that doeth them shall live in them.
Galatians 3:12 (KJV)
Anytime we are looking to our works or efforts as the reason for why we should be blessed, we are not operating in faith. Faith is to remove ourselves from the equation, and to look only to Jesus. Because of the finished works of Jesus the blessing has been made available, and faith is to be open and receptive to it manifesting in our lives.
