Because God IS. God just IS. God is a WORD, for whatever we are or were or will be. You call him Jesus, i call him God, others call him by other names. God is such a general word, when someone says, "do you believe in God?" most will say "yes," no," or "not sure." Not, "well, i believe in God, but not the traditional Christian Version." or "I believe in God, but not the traditional Buddhist version." Nine times out of ten you will get a yes, no, or not sure. That's what i mean. We both believe in God.
