"I AM." —Exodus 3:14
Moses was reluctant to accept God's mission for him because He was asking the question: "Who am I?" (Ex 3:11) Moses was a stuttering, old shepherd wanted for murder in Egypt. Who was he to "go to Pharaoh and lead the Israelites out of Egypt?" (Ex 3:11)
After asking the wrong question, Moses asked to know God's name (Ex 3:13). In other words, he asked to know Who God is. That is the question. When we ask "Who is God?", we receive the answer that God is I AM WHO AM (Ex 3:14). He is the eternal, all-holy, almighty Source of life. Because of Who God is, He can do anything and those sent by Him can do the humanly impossible.
Think of the most difficult situation in your life. Possibly it is your marriage, family, health, or an addiction. Think of the devastating tragedies which make up our culture of death — abortion, abuse, violence, racism, starvation, pornography, etc. If you ask the question: "Who am I?", you will be paralyzed into passivity. If you ask the question: "Who is God?", you will be zealous for the Lord and more than a conqueror (Rm 8:37). Look to God, not to self. Ask the right question.
