What's the Point?
The signs that Jesus gives throughout th Gospel of John are all meant to create faith, belief and worship of Christ in the heart of those who witness them. The signs that Jesus does are not simply for the entertainment or material benefit of those around. These signs are meant to create faith in Jesus Christ. The Jews wanted signs so that they may believe, rather than believing His word about himself. This Gentile official showed more faith in Christ than the Jews who knew Him best. The official took Jesus at His word and believed that He would do what He said He would do.
