1 Corinthians 14:4-5
14:4 The one who speaks in a tongue builds himself up, but the one who prophesies builds up the church.
14:5 I wish you all spoke in tongues, but even more that you would prophesy. The one who prophesies is greater than the one who speaks in tongues, unless he interprets so that the church may be strengthened.
1 Corinthians 14:12
14:12 It is the same with you. Since you are eager for manifestations of the Spirit, seek to abound in order to strengthen the church.
1 Corinthians 14:26
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.
