 It's that simple. A relationship you were created for that you don't have, that you can have, that you must choose. That's life or death information. Eternal life or death. It isn't so much that Jesus is asking you to go out on some witnessing raid of people you don't know. He wants you to do what you already do every day for eternity by trying to take some of the people you're with all the time to heaven with you.
