1 Corinthians 12:
4 Now there are diversities of gifts, but the same Spirit.
5 And there are differences of administrations, but the same Lord.
6 And there are diversities of operations, but it is the same God which worketh all in all.
The word "worketh" in 1 Cor 12:6 is the Greek word energōn (from the root energeō) and it means to energize. God is the One Who works within the believer to bring what is needed to the body of Christ.
The varieties of gifts of vs 4, the different ministries within the church of vs 5, and the various activities of vs 6 are all energized by the same God Who works all the gifts, ministries, and activities in all believers.
Since it is God Who energizes all in all, who are we to forbid His energizing?
We have no problem when God works within the believer to bring exhortation to the body (Rom 12:8). Why do we have a problem when God energizes tongues?
