To share our faith effectively, we must let people know that we are not "weirdoes" or religious fanatics. We must show them that we care, and we start by being friendly. A shy person once began greeting people by going to a park on a Saturday afternoon just to practice being friendly to strangers. He and a friend had so much fun that they couldn't wait to get out the following weekend to take the next step and actually witness to people. Try doing that, and when you have gained a measure of confidence, you can swing to the subject of spiritual things. It's not wise to walk up to people and immediately talk about Jesus. They'll most likely think you're strange. Instead, start with everyday things and then swing to the spiritual realm. That's what Jesus did in John chapter 4. There goes another minute. Gone forever. Go share your faith while you still have time.
