What does 1 Corinthians 14:39 mean?
In wrapping up this section, Paul returns to where he began his teaching about the use of spiritual gifts in the church service. In verse 1, he encouraged the Christians in Corinth to earnestly desire the gift of prophecy and now he does so again.This gift, given by the Holy Spirit to believers, involved proclaiming revelation from God to others for the purpose of building them up. Before the Scriptures were available, this was one method by which God communicated truth to His people. Some churches believe that God continues to regularly communicate in this way. Other churches believe this gift is not normally distributed by God, mostly replaced by the gift of teaching Scripture.
Paul has emphasized in this section that the gift of prophecy is more beneficial for the church than the gift of speaking in unknown languages. Still, he expressed his desire that all the Christians in Corinth would be able to speak in tongues (1 Corinthians 14:5). Now he makes clear once more that he is not forbidding anyone from exercising this gift, in general, aside from the restrictions he gave them for the use of the gift in church services (1 Corinthians 14:26–28).
He repeats the main principle behind his instructions for church services in the following verse.
