The purpose of the Gospel of John is recorded in John 20:21. This is our benediction for this historic day when we remember the tragic terrorists attack on our country on September 11, 2001.
"But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through His Name" (KJV).
"But these are written (recorded) in order that you may believe that Jesus is the Christ (the Anointed One), the Son of God, and that through believing and cleaving to and trusting and relying upon Him you may have life through (in) His Name" [through Who He is]. [Ps 2:7,12.]. [AMP]
