Imagine giving up your life to follow a singular person because he has done amazing miracles in front of you. This person, Jesus, claimed a lot of things. He claimed not only to be the Son of God, but in so doing claimed to be Yahweh himself, the covenant God of Israel.
As we study John 18-21, we'll see how the disciples lived and walked with Jesus, and how we too can follow closely after our Savior.
