Ephesians 4 vs 10, Song of Solomon 2, 3
Ephesians talks about the parts of the body of Christ, some as evangelist, others as prophets, teachers and they work as the body does like the hand works with the chest to move likewise as the feet cannot say to the toe it is useless. The fundamental idea is every part of the body of Christ even the small part we deem useless are the most useful. So no matter the work we do for God no matter how small it is, it is useful to the body of Christ.
Some people say those who donate never do anything, some say those who teach like the lime light, some say those who pick up the communion plates after communion are not useful. But in the eyes of God, all are equally useful. Because we as believers as fitly joined together.
