Some of Jesus' disciples did not understand, became offended and stopped following him. Just the day before, Jesus had fed them in a miraculous way, proving that his power came from God. So why did they abandon him? Apparently, they were following him for selfish reasons. They expected Jesus to meet their physical needs.
The question arises, "Why do I follow Jesus, do I do it primarily for present and future blessings, or because I love God and desire to please him?"
