Jesus said therefore to the twelve, "You do not want to go away also, do you?" Simon Peter answered Him, "Lord, to whom shall we go? You have the words of life. And we have believed and have come to know that You are the Holy One of God." (John 6:67-69)
Peter understood and truly believed that Jesus was the Messiah. Prior to this, many of those who had begun to follow Jesus had withdrawn and no longer followed Him. Does your belief allow you to follow Jesus regardless of the circumstance you find yourself in?
