Clearly, the person who spoke in tongues would in some way be built up by this gift. Perhaps it would bring him comfort and encouragement to see this evidence of the Spirit’s work in his life. Yet, while it is a good thing to build up oneself in the faith, it is better to build up one’s fellow believers. Love seeks the good of others (1 Corinthians 13:4–7).
4 The one who speaks in a tongue builds up himself, but the one who prophesies builds up the church.
