It is the cry of the human heart. I think at some point all of us are desperate to find out who we are. It is the search for identity. It is a search for what has been stolen from us.
We have been told lies about who we are and who we belong to. What have you been told in your life that made you doubt the goodness of God?
Moses heard what God had planned for him and he was filled with thoughts of inadequacy. It completely overwhelmed and paralyzed him. Maybe God is calling you and you feel so unworthy to measure up to the call you have in your heart.
The bad news: You are unworthy. We ALL are. The great news? God wants to use us anyway.
That is the an incredible truth and it tells you the most about who you really are. You are the chosen agent designed to reflect God's beautiful love and character.
