Note 21 at 1Co 14:17: This is a very powerful benefit of speaking in tongues (see note 4 at 1Co 14:2). When we speak in tongues, we are praising God, and since we are praying from our spirits (see note 18 at 1Co 14:14), we don't experience the hindrances that are present when we pray from our minds. We are giving perfect praise unto God, without the limitations of human language or thought. If there were no other benefits associated with speaking in tongues, this would be more than enough reason to seek this gift.
