If you are a human being that can Say "I AM" then you are invoking God every time you say "I AM"

 This is my experience. There is something about saying "I AM" as in "I AM HERE" so when you say: 

"I AM Here" you are invoking God to be here where you stand right now. If "I AM" is the name of God and I believe this to be true when you say "I AM" or "I AM HERE" God manifests through you in those moments when you say this. 

By God's Grace
