“I AM” is a name that God chose for Himself in scripture. Exodus 3:14 reads: “And God said unto Moses, I Am That I Am: and he said, Thus shalt thou say unto the children of Israel, I Am hath sent me unto you.”
The Bible teaches that God was and always is.
The pictures around it are also representative of names of God: Jesus is the way, the truth, and the life (see John 14:6). He lives in our hearts (when we become His children, see Galatians 4:6). He is King of kings (see 1Timothy 6:15). He is the light in the darkness (see John 12:46). Jesus was poured out as an offering in His death on the cross, and this is why we celebrate communion as Christians (see Matthew 26:26-28). He is the light of the world (see John 8:12). He is true to His promises, (rainbow is a symbol of His promise to Noah and the earth, see Genesis 9:14-15).
