Thomas is the illustration used for this session. He actually demanded to have physical verification of Christ's resurrection before he would believe. When Jesus suddenly appeared, he fell down before Him exclaiming, My Lord and my God. A lot of people claim to have faith but cannot tell you the object of their faith. Faith without an object is no faith at all. In short, faith is simply taking God at His Word and acting upon it. When witnessing to the lost, we ought to ask: What would it take before you will believe and trust Jesus Christ as your own personal Lord and Savior.
