1 Corinthians 14:4-5

One who speaks in a tongue edifies himself; but one who prophesies edifies the church [promotes growth in spiritual wisdom, devotion, holiness, and joy]. Now I wish that all of you spoke in unknown tongues, but even more [I wish] that you would prophesy. The one who prophesies is greater [and more useful] than the one who speaks in tongues, unless he translates or explains [what he says], so that the church may be edified [instructed, improved, strengthened].
