I love discussing faith with people of no faith. It's one of the great joys of life as a follower of Jesus. Where I find it hardest to help is where the genuine seeker is stuck in their search, having tried everything thoughtfully, carefully and prayerfully.
Where I find it easiest is where the people of no faith have as many misunderstandings about the nature of the Bible as here. Pop along to this site which offers 50 'proofs' that God is imaginary. See how long it takes you mentally to demolish each one. Some will take as long as ten seconds.
