sense if there is not Someone to call us to account. Above all the life and teaching of Jesus Christ proves that there is a God. His teaching demonstrates that He was a moral genius, but no one who was a moral genius could have made the claims that Jesus made unless they were true. May I suggest that. staring with the Gospel of John, you read the Gospels through asking God as you do so to show you the truth through them. Then you will know for yourself that God is true.
