My friends, when you meet to worship, you must do everything for the good of everyone there. That's how it should be when someone sings or teaches or tells what God has said or speaks an unknown language or explains what the language means.
My friends, what good would it do, if I came and spoke unknown languages to you and didn't explain what I meant? How would I help you, unless I told you what God had shown me or gave you some knowledge or prophecy or teaching?
