God was saying, ‘I want you, David, I want everything you have and everything you are.’ At that moment God did not say, ‘You’re going to be a preacher, you’re going to be an evangelist, you’re going to be a missionary.’ It was to say, ‘David, I want all – or nothing,’ and I was just 15 years old!

That’s where we begin with God – it’s all or nothing. You can’t play with God; you can’t fool with Him. What are you called for? Are you called to live for God, or for yourself – to have a good time, a family and a big house, a car and a successful business and just to go on until your pension comes? No, when God called you, He said, ‘I want everything, including your success.’
