The devil was saying, ‘Don’t listen to God, you are doing enough. You are a Christian, preaching the Gospel; that is enough.’ And God said, ‘No, it isn’t!’ He said to me, I want you! I could get no peace until I turned to the Lord and surrendered everything to Him. God did not tell me to be an evangelist. He didn’t call me to be a pastor. What God said to me that day, when I was 15 years old, was, ‘David, I want you; I want all of you; I want your life, your time, your money.’
