Matthew Henry Commentary John 20:30-31

"Many other signs therefore did Jesus in the presence of the disciples, which are not written in this book: but these are written, that ye may believe that Jesus is the Christ, the Son of God; and that believing ye may have life in his name." — John 20:30-31 (ASV)

There were other signs and proofs of our Lord's resurrection, but these were committed to writing, that all might believe that Jesus was the promised Messiah, the Saviour of sinners, and the Son of God; that, by this faith, they might obtain eternal life, by his mercy, truth, and power. May we believe that Jesus is the Christ, and, believing, may we have life through his name.
