As they were going along the road, they came to a place where there was some water. The official said, "Look! Here is some water. Why can't I be baptized?"
Those flood waters were like baptism that now saves you. But baptism is more than just washing your body. It means turning to God with a clear conscience, because Jesus Christ was raised from death.
If we have faith in God's Son, we have believed what God has said. But if we don't believe what God has said about his Son, it is the same as calling God a liar.
