More than a third of British young people now claim to be either atheists or agnostics.

Mal Fletcher, director of Next Wave International, says: 'I'm not so sure that more people are becoming athiests in their heart of hearts.'

'People deep down still long to believe that we're more than cosmic orphans alone in a meaningless and absurd universe.'

'But atheists are becoming more strident, even more evangelistic in their efforts to recruit others to their cause.'

In a powerful address to several thousand people at Hillsong Church, London, last week, Mal made the case for a rational belief in the God of the Bible.

In the session entitled 'Why I Believe in God', Mal said: 'Many people still hold that science is the bastion of atheism and naturalism; that it has no place for God.'

'Actually, they're behind the times. There is growing evidence in almost every field of contemporary science for a belief in the existence of a supreme being -- from cosmology and astronomy, to micro-biology and the study of human consciousness.'

In this session, in one of London's largest theatres, Mal looked at the different 'options' for belief in God among the world's leading religious faiths.

'In the end,' he said, 'what you discover about God comes down to what you do about Jesus Christ.'

'He took our concept of God to an entirely new level. No other religious leader or philosopher so fully answers the questions: "What is God like and, more importantly, is he interested in me?"'

Mal looked at the historical proofs for the existence of Jesus, and his impact on history -- and his unique claims as the Son of God.

After the session, scores of people responded to the challenge to accept Christ, for the first time.
