God of the living is the name that Jesus (Yeshua‘) gave to His Father when He was discussing resurrection with the Jewish religious leaders. His argument was that since God introduced Himself to Moses as the God of Abraham, and the God of Isaac, and the God of Jacob, those men were still living with Him.

He is not the God of the dead, but the God of the living: ye therefore do greatly err. (Mark 12:26-27 KJV)
A similar name of God is Judge of the living and the dead. Jesus is Lord both of the dead and of the living and He introduced Himself saying, I am the resurrection and the life.
