Jesus said to the twelve disciples, “Do you want to go away as well?” Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life, and we have believed, and have come to know, that you are the Holy One of God.” (John 6:67-69)
Not all the listeners understood Jesus’ message that faith means that the kingdom of God dawns through those who believe. They turned away from Jesus.
Jesus also asks the disciples if they want to go as well. Peter sums up the meaning of faith very well. Even if we do not understand everything, we trust Jesus because in him we meet God, and he gives us eternal life.
