I am reading 1 Corinthians chapter 14. A few questions came to my mind. Below is one of them. I will open another thread for another question. It sounds Paul is saying tongues are not a sign for believers, but for unbelievers. But then he says, if an unbeliever enters a Church where everyone is speaking in tongues, they would be confused and think people are out of their minds. Are tongues sign for unbelievers or not? Same way, the verses are a little confusing for me about prophesy as well. How do I interpret these verses? I read a commentary on ESV study bible. I am posting that also. But I would love to hear everyone's thoughts on this 1 Corinthians 14:22-25 ESV Thus tongues are a sign not for believers but for unbelievers, while prophecy is a sign not for unbelievers but for believers. If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your minds? But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all, the secrets of his heart are disclosed, and so, falling on his face, he will worship God and declare that God is really among you. Commentary - 1 Cor. 14:22–25Thus tongues are a sign … for unbelievers. Not a positive sign, to lead people to faith (as in John 2:11; 20:30–31), but as in1 Cor. 14:21 a negative sign that facilitates God’s judgment on the unbelieving. Uninterpreted tongues function as a sign of judgment for the outsider and unbeliever because they may conclude from hearing them that Christians are out of their minds and so leave the church, never to return.prophecy is a sign … for believers. Although the purpose of prophecy is primarily for the benefit of believers, prophecy (unlike tongues) also has the secondary benefit of convicting the unbeliever, exposing the secrets of his heart and causing him to worship God. When believers see this happen, prophecy encourages them that God is at work, and thus it serves as a positive “sign” of God’s blessing on the congregation (a “sign” in Scripture can be either positive or negative; cf. Ex. 8:23; 10:12; Luke 21:11; Rom. 15:19).
