1 Corinthians 14:24-26
14:24 But if all prophesy, and an unbeliever or uninformed person enters, he will be convicted by all, he will be called to account by all.
14:25 The secrets of his heart are disclosed, and in this way he will fall down with his face to the ground and worship God, declaring, “God is really among you.”
Church Order
14:26 What should you do then, brothers and sisters? When you come together, each one has a song, has a lesson, has a revelation, has a tongue, has an interpretation. Let all these things be done for the strengthening of the church.
