The real reason…
People can get excited about our experiences, especially when they seem so real to us that we lose all inhibition in sharing it with anyone and everyone. It is a powerful witness when someone actually radiates conviction about what they are saying to you. Jesus exposes us, and we go and expose Him. We are lit up and on fire, and we use all the heat we can to bring people to the Light that has found us.
Now some people won’t care about that and they might dismiss you as a raving lunatic. Others, out of curiosity, will go and see for themselves what all the fuss is about, even if just for a laugh. However, there are people who know you and they will pay closer attention, especially people who know that you are the sort that usually hides their faults (and that’s all of us, by the way). They will be eager to see just what all the commotion is about. They will see a real change, and want to see for themselves if this is the real deal or not. When they meet Jesus for themselves, the word they began to believe because they believe in you will become most real to them.
They believed because of his word. It is not your words or your experience that makes them trust Jesus. This can get them to the table but only the real Word will get them to eat. Hearing about change in your life is one thing, experiencing it firsthand is the best thing. The real reason people believe Jesus is that they have fallen into the well, too. Bring them to the well of His Word, and pray that they will hear His call in the bottom of their souls.
