After Jesus turned water into wine, John says,
“This beginning of signs Jesus did in Cana of Galilee, and manifested His glory; and His disciples believed in Him” (John 2:11).
Jesus already had disciples, who followed Him because of His teaching, but when they witnessed His first miracle, they believed in Him. They already believed Him, but they then began to believe in Him in a greater way, for this manifestation of His glory showed Him to be more than a man.
What have you concluded about Jesus? Are you following Him?
