Christ performs the miracle, but for both practical and spiritual reasons, His disciples present the food to the people. It was more organized and took less time to distribute the food this way than by doing it Himself. More importantly, Jesus and His disciples were becoming a team, and it was essential that they share in His work to have firsthand experience. Their involvement in Christ's generous, compassionate, loving act of providence would be a lasting memory to fuel their faith and zeal in their future apostolic work.
Jesus' miracle provided them an opportunity to serve Him, while teaching us lessons in responsible service. Though God does not need us, He gives us the privilege and blessing to be involved in His service. Some people do not wish to be encumbered by a duty at church, but this is a wrong perspective of service. God provides opportunities to serve so that we might experience great blessing.
The disciples had a responsibility to give to the people what Christ had given them. When God gives to us, we are to share faithfully with others, not hoard His gifts for ourselves. Ministers are to preach the whole truth of God and not change the message or withhold parts of it (Acts 20:27). Church members should look out for the welfare of others, sharing our blessings. If we are wealthy with every spiritual blessing (Ephesians 1:3), we should pass them on to others by living God's way of life as a witness.
