1 Cor 14
“If you speak to people in words they don’t understand, how will they know what you are saying? You might as well be talking into empty space. There are many different languages in the world, and every language has meaning. But if I don’t understand a language, I will be a foreigner to someone who speaks it, and the one who speaks it will be a foreigner to me.And the same is true for you. Since you are so eager to have the special abilities the Spirit gives, seek those that will strengthen the whole church. So anyone who speaks in tongues should pray also for the ability to interpret what has been said…If unbelievers or people who don’t understand these things come into your church meeting and hear everyone speaking in an unknown language, they will think you are crazy.
Well, my brothers and sisters, let’s summarize. When you meet together, one will sing, another will teach, another will tell some special revelation God has given, one will speak in tongues, and another will interpret what is said. But everything that is done must strengthen all of you…No more than two or three should speak in tongues. They must speak one at a time, and someone must interpret what they say. 28 But if no one is present who can interpret, they must be silent in your church meeting and speak in tongues to God privately…Or do you think God’s word originated with you Corinthians? Are you the only ones to whom it was given?If you claim to be a prophet or think you are spiritual, you should recognize that what I am saying is a command from the Lord himself. But if you do not recognize this, you yourself will not be recognized.[So, my dear brothers and sisters, be eager to prophesy, and don’t forbid speaking in tongues. But be sure that everything is done properly and in order.”
The context of the whole passage of 1 Cor 14 is about orderly worship. It clearly stated that at most 3 can speak in tongues and with interpretation, otherwise none should speak. It does not edify anyone who may not understand, much less the unbelievers who turn up and may think everyone has gone crazy.
It is clear from 1 Cor 14:37 that orderly worship is a command from the Lord. Yet we see the blatant disobedience in some charismatic worship services when many just blabbered away in unintelligible tongues and laugh uncontrollably.
Cain offered an unacceptable sacrifice as compared to Abel. Heb 11:4. That is the way of Cain who worship God to his own whim and fancy.
