What are are Commitments and Agreements that we make?

I have been listing to a book on iTunes by John Eldrenge Waling with God check out there web page hear http://www.ransomedheart.com/ One of the things that the author spoke about was commitments or agreement. In the approach I use I use the term life depends on? Or my greatest perceived threat is? Life Depends on? yet I have felt that I been missing something and when John spoke about agreement and commitments that rang so true. What do we really believe about our self and what will happen in our live. I have meat so many people who say " I suck" " I will never be loved" those are agreements that we make and they come from the evil one. They are lies. We are created in Gods image and we have value. We were woven in our mothers wombs by God Psalm 139. He know us and made us the way we are and it was good. So many times we go through life and what happens to us is that others interpret life for us and we pick up the message that "I suck" "no one will love me" and if we go unchecked we come to believe that this is so and its true. These commitments rob of of connection with others and kill our soul.
