God has designed the local church like a physical body, with Jesus Christ as the head. God gifts each of His children in unique and special ways to serve and build up the body. Therefore, spiritual gifts are not for personal benefit or glory, but to bring glory to God, as well as encouraging and building up the church. 1 Corinthians 14:4
No one individual can have all the gifts. 1 Corinthians 12:17-30. We are interdependent on each other; together we are the body of Christ which is a clear demonstration of true diversity. There is no division as we all have equal concern and need for each other. One is an eye, another is a hand, another is a foot; and some are presentable while other parts are un-presentable.
We all must be the part God has designed us to be, if not, the body suffers and becomes ill. “If a man’s gift is prophesying, let him use it in proportion to his faith. If it is serving, let him serve; if it is teaching, let him teach; if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully.” Romans 12:6-8
God gives rules in His word for the use of tongues. If someone speaks in a tongue it will be one at a time. 1 Corinthians 14:27. There must be an interpreter. 1 Corinthians 14:28. There must be one who discerns whether it comes from God. 1 John 4:1.
