Oklahoma Howdy to Nancy8867,
I sincerely hope you enjoy Christians Unite. You will find numerous posts on Christians Unite that deal with witnessing, but this topic really deserves a separate thread. I would love to see you start this thread. I think that it would be a great discussion that many people are interested in.
I honestly think that God gives His children opportunities to witness. It's just a matter of listening and recognizing it. Some situations would be much more difficult than others. When someone is down, talking about a crisis, or some other monstrous and negative event, that may be an opportunity God gave you to witness. You might start with something as simple as, "Jesus can give you strength, comfort, and guidance. Do you have Jesus in your heart?"
I look forward to reading your posts.
In Christ,
Tom
