I serve the Lord with gratitude; I didn't choose Him, He chose me and appointed me that I should go and bear fruit, and that the fruit should remain. From childhood, I wanted every day and every part of my life to be under the direction and control of the Holy Spirit. Now when I look back over 70 years of ministry I know with absolute certainty that there has been both purpose and direction in my life. God has been in control of all my days and all my experiences. Everything that has happened in my life was foreknown in His plan.

When I was a teenager, God so impressed on me Romans 12:1: ‘I beseech you, present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.’ (KJV.) God is talking about ‘normal’ service, nothing exceptional – for every believer – the ‘norm’! Today the churches talk about being ‘normal’, take care of yourself, don’t work too hard... But the challenge given by Paul is that ‘reasonable’ service – means giving your WHOLE life as a ‘living sacrifice’! EVERYTHING! Give God EVERYTHING! God did not call me to be an ‘evangelist’ or ‘preacher’ – He said He wanted ALL of me!

A spiritual battle started in my life. I knew that the Lord was calling me, challenging me, ‘David – I want YOU!’ But the devil was saying, ‘Don’t you realise you’re saved, you got baptised in water, filled with the Holy Spirit – that’s enough!’ But God was saying, ‘David, I want YOU, all of you, EVERYTHING! – Your life, your family, your time, your house, every single thing – I want the lot!’ I had no peace until that night I gave Him everything.
