The ground we have in common with unbelievers is not the Bible, but our common needs, hurts, and interests as human beings. You cannot start with a text expecting the unchurched to be fascinated by it. You must first capture their attention, and then move them to the truth of God's Word. By starting with a topic that interests the unchurched and then showing what the Bible says about it, you can grab their attention, disarm prejudices, and create an interest in the Bible that wasn't there before.
Rick WarrenWorship is a powerful witness to unbelievers-if God's presence is felt, and if the message is understandable. God's presence must be sensed in the service. More people are won to Christ by feeling God's presence than by all our apologetic arguments combined. Few people, if any, are converted to Christ on purely intellectual grounds. It is the sense of God's presence that melts the heart and explodes mental barriers.
