23 If, then, the whole church meets together and everyone starts speaking in strange tongues — and if some ordinary people or unbelievers come in, won't they say that you are all crazy?
24 But if everyone is proclaiming God's message when some unbelievers or ordinary people come in, they will be convinced of their sin by what they hear. They will be judged by all they hear,
25 their secret thoughts will be brought into the open, and they will bow down and worship God, confessing, “Truly God is here among you!”
26 This is what I mean, my brothers and sisters. When you meet for worship, one person has a hymn, another a teaching, another a revelation from God, another a message in strange tongues, and still another the explanation of what is said. Everything must be of help to the church.
27 If someone is going to speak in strange tongues, two or three at the most should speak, one after the other, and someone else must explain what is being said.
28 But if no one is there who can explain, then the one who speaks in strange tongues must be quiet and speak only to himself and to God.
29 Two or three who are given God's message should speak, while the others are to judge what they say.
