1 Corinthians 14:4-5

The one who prays using a private “prayer language” certainly gets a lot out of it, but proclaiming God’s truth to the church in its common language brings the whole church into growth and strength. I want all of you to develop intimacies with God in prayer, but please don’t stop with that. Go on and proclaim his clear truth to others. It’s more important that everyone have access to the knowledge and love of God in language everyone understands than that you go off and cultivate God’s presence in a mysterious prayer language—unless, of course, there is someone who can interpret what you are saying for the benefit of all.
