According to Merriam Webster a committee is defined as "a body of persons delegated to consider, investigate, take action on, or report on some matter." Maybe "committee" sounds too official and proper for church; but as we are to be stewards of God's possessions, we can do this more efficiently by having church members serve where their gifts are best utilized.
"There are different kinds of gifts, but the same Spirit distributes them. There are different kinds of service, but the same Lord. There are different kinds of working, but in all of them and in everyone it is the same God at work." - 1 Corinthians 12:4-6
"Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms." - 1 Peter 4:10
"Serve wholeheartedly, as if you were serving the Lord, not people." - Ephesians 6:7
There are six different committees / teams / groups at Cedar Grove that are involved in non-spiritual aspects of furthering God's kingdom.
