Three "invitations" stand out in John's Gospel: "Come and see" (John 1:39); "Come and drink" (John 7:37); and "Come and dine" (John 21:12). How loving of Jesus to feed Peter before He dealt with his spiritual needs. He gave Peter opportunity to dry off, get warm, satisfy his hunger, and enjoy personal fellowship. This is a good example for us to follow as we care for God's people. Certainly the spiritual is more important than the physical, but caring for the physical can prepare the way for spiritual ministry. Our Lord does not so emphasize "the soul" that He neglects the body.
When we care then we can share!
