1 Corinthians 14:6 MSG

[6] Think, friends: If I come to you and all I do is pray privately to God in a way only he can understand, what are you going to get out of that? If I don’t address you plainly with some insight or truth or proclamation or teaching, what help am I to you? If musical instruments—flutes, say, or harps—aren’t played so that each note is distinct and in tune, how will anyone be able to catch the melody and enjoy the music? If the trumpet call can’t be distinguished, will anyone show up for the battle?
