“I am who I am” is important for today’s Christian to understand the complexity of who God is.  He is all encompassing and self-sufficient.  It is a name above names, one that reminds the believer that God is in control, and that He sees His children.  “I will become what I choose to become,” “I am what I am,” “I create whatever I create,” or “I am the Existing One.”  Its context is the encounter of the burning bush.  Moses asks what he is to say to the Israelites when they ask what God has sent him to them.
