Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
Believing in Jesus brings eternal life.
There is a lot more that goes into being a disciple than that, but there is NEVER anything less than that!
It all starts with believing that Jesus saves.
Life is found in His Name.
