30 Do we all have the gift of healing? Do we all have the ability to speak in unknown languages? Do we all have the ability to interpret unknown languages? Of course not!
Speaking in tongues should be done with interpretation.
1 Corinthians 14:27–28 (NLT)
27 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.
Prophecy is better.
1 Corinthians 14:18–19 (NLT)
18 I thank God that I speak in tongues more than any of you.
19 But in a church meeting I would rather speak five understandable words to help others than ten thousand words in an unknown language.
