When parents understand the source of joy, when they decide to let Christ rule in their home, they have chosen the way of joy that will never disappoint them. Billy Graham's parents were both committed Christians. Although he was a businessman, his father had at one time felt a desire to preach. The way never seemed opened for him. After Billy entered the ministry, the father said, "I prayed for years for a way to be opened. But never once was there the slightest encouragement from God. My heart burned and I wondered why God did not answer my prayer. Now I feel I have the answer. I believe that my part was to raise a son to be a preacher." Imagine the joy that thought brought to him and to his wife.
