Is the confession of John the Baptist, combined with the affirmation of God, enough for you to believe that Jesus is the Son of God?  Or, do you still need Jesus to perform for you in order that you can be convinced that He is who He said He is?  John the Baptist's testimony is so clear that we must be willing to admit, to confess, and to see Jesus as Lord - else we too will incur the wrath of God for the sins we refuse to repent from.
