New Defender's Study Bible Notes
20:31 that ye might believe. Here John states that his specific purpose in writing was to win people to Christ. It is very significant that the divinely inspired method of doing this (as well as serving as an authoritative guide for methods of evangelism today) began with a strong affirmation of the special creation of all things by Christ, followed by a strong presentation of the program of redemption. In addition to the evidences provided by the miracles performed by Christ, John stresses the evidences of His resurrection and victory over death—especially the evidence of the empty tomb (John 20:8) and the post-resurrection appearances (John 20:20, etc.). Finally, the written Word itself gives abundant evidence of inspiration, and thus itself is a strong evidence (John 20:31).
