God Almighty is the name that Abraham, Isaac, and Jacob all used to refer to God, and not Lord. Genesis 35:11 God talking to Abraham refers to Himself in this way: "I am God Almighty..." and again in Genesis 17:1 before the changing of Abraham's name from Abram, God speaks to Abram saying " I Am God Almighty; walk before me and be blameless." In this case God names Himself as Almighty, as it is said assuring Abraham of His great power. The Hebrew translation is El Shaddai, referring to Himself twice as "El" means God and Shaddai meaning one who provides, and is all sufficient, and is mighty to protect. Matthew 16:15 Jesus asks His disciples "But who do you say I AM?" Even in His question to the disciples, He reveals who He is: "I AM".
