Use and Purpose of Tongues, Prophecy, and Serving

The giftedness to apostles, speaking in tongues, prophecy, and miracles were necessary as the early church was being established. With the completion of the canon of Scripture those gifts ceased.

The Spirit is the member of the Godhead who dispenses spiritual gifts for the common good of the local church members. The gifts are not primarily to benefit the individual gifted with them, but are for the edification of the body by serving one another.

Serving in the body is then primarily done in the realm where God has dispensed a measure of faith. The measure of faith being that special ability to trust God and rely upon Him in the use of that giftedness to serve the body.
