Billy Graham says: "As an evangelist, I have often felt too far spent to minister from the pulpit to men and women who have filled stadiums to hear a message from the Lord. Yet again and again my weakness has vanished, and my strength has been renewed. I have been filled with God’s power not only in my soul but physically. On many occasions, God has become especially real, and has sent His unseen angelic visitors to touch my body to let me be His messenger for heaven, speaking as a dying man to dying men."
