A helpful entry by Matt Adair is entitled: Re-Thinking Evangelism.
He insightfully states:
I’ve been through more than a few evangelism training courses and I have yet to come across one that doesn’t fail on the basic level of turning into a sales pitch. And here’s one reason I think that is – to the degree that the gospel is not our operating principle in life, we’re sharing a product and not our lives. And if we do try to share our life and not sell an evangelistic product, we ultimately don’t have anything sturdy enough to give to people.
