Although there may be nothing wrong with platitudinous prophecy, it is not the type of prophecy that Paul commends to the church in 1 Corinthians 14:24-25. In that passage, Paul says: “But if all prophesy, and an unbeliever or an ungifted man enters, he is convicted by all, he is called to account by all; the secrets of his heart are disclosed; and so he will fall on his face and worship God, declaring that God is certainly among you.”
In 1 Corinthians 14:2, Paul clearly teaches, “For one who speaks in a tongue does not speak to men but to God…” In direct contradiction of this clear statement by Paul, most Pentecostals teach that according to 1 Corinthians 14:5 tongues plus interpretation equals Prophesy. First of all, Paul is not addressing tongues, interpretation or prophecy in 1 Corinthians 14:5, but the edification of the Church. He is not contradicting himself by saying that interpreted tongues are prophesy, he is saying that only when tongues are interpreted do they edify the church like prophesy, which needs no interpretation.
If when we speak in a tongue we speak to God, then the interpretation must be speaking to God or it is not an interpretation.
You may be asking why this is important. It is important because somehow; unbelievers, the ungifted, and young people raised in Pentecostal churches, sense that misuse of gifts of the Spirit, like a message in tongues interpreted as a prophecy are improper. Experiencing improper manifestations of the gifts of the Spirit is used powerfully by Satan to drive many people away from pursuing the Promise of the Father. I don’t for a moment believe that Pentecostals intentionally misuse the gifts of the Spirit. They are only doing what they have seen and heard others do for decades. Check out my book, The Promise of the Father for a more detailed discussion of this problem and its solution.
