1 Corinthians 14:23-25

1Co 14:23 For this reason, if the whole assembly comes together, and all of you are speaking in other languages, and newcomers or unbelievers come in, would they not say that you are all maniacs?
1Co 14:24 But if you all are prophesying, and some unbeliever or newcomer comes in, he is going to be convicted by you all, his resolve will be challenged by you all.
1Co 14:25 The things hidden in his heart will become exposed, and as a result he will fall facedown and worship God, announcing, “God is really among you.”

what if everybody…

Paul has been addressing a problem that had developed in Corinth. Some of the members of some of the fellowships had started bursting out in praise and prayer in other languages. The worshipper himself knew what he was saying, but nobody else did. It was causing confusion. At this point in his argument, Paul stops and asks “What if everybody was doing what you are doing?” If everybody was prophesying, it would lead to conviction and conversion. But if everybody was babbling in unknown tongues, it would turn newcomers and unbelievers off to the gospel, and turn them off to the church. They would think it was a church full of maniacs. It matters what you do in church.

LORD, give us the wisdom to display your wisdom when we worship.
