In the Old Testament book of I Chronicles, chapters 25, 26 & 27 lay out a plan that includes a specific function for every family and each member of those families for the entire tribe of Israel. Each one supplying what they are gifted and anointed to do best, means that the entire tribe of Israel has all of it's needs met by its own members. They don't need anyone outside of themselves, when they function in the way God set them up to do. He is the Head, they are the body.
The Apostle Paul sets up a similar idea in Romans 12 and I Corinthians 12.
Christ is the Head of the Body, and we each individually as followers of Christ have gifts and are anointed to function in a way that builds up and strengthens the Body of Christ. No one gift or function is of any greater significance or importance than another, but all are necessary to the healthy working of the body as a whole.
Praise God, Who is Wisdom beyond our understanding, and always does what is BEST for His children!
