I went to a friends baptism, I was a non believe who knew very little of Jesus and Christianity except that it was boring and I wanted nothing to do with it. However, I listened to the testimonies given, of how people came to believe in Jesus, and it hit me.....these people really think they know Jesus personally and that knowing him has made a difference in their lives. They were all nice, sensible people like me, not deluded or stupid. The pastor was speaking about depression and how we try to fill our sadness with drink or drugs, sex or money, but only Jesus will fill the gap. I felt as though he was talking directly to me, although I had never met him before. When he asked if anyone wanted to be blessed by Jesus, this Jesus I didn't believe in, I raised my hand, and BAM I was filled with a feeling of incredible and overwhelming love and peace, and I knew that I too had met Jesus!
Hope this helps.
