This tract by Charles Leiter focuses on the claims which Jesus made about Himself and attempts to show that an honest assessment of the evidence will not allow us to think of Jesus as merely a good teacher, but requires us either to worship Him as Lord or dismiss Him as a liar or lunatic. (Fans of C. S. Lewis will recognize this argument, and Leiter even quotes Lewis at the conclusion.) Most importantly, the verses used also present the basic substance of the gospel as the tract progresses. The tracts are printed in a small, sturdy, trifold format, so they are easy to carry around.
Scripture quotations are from the NASB (updated edition).
