1 Corinthians 14:1, 4, 22

Pursue [this] love [with eagerness, make it your goal], yet earnestly desire and cultivate the spiritual gifts [to be used by believers for the benefit of the church], but especially that you may prophesy [to foretell the future, to speak a new message from God to the people].

One who speaks in a tongue edifies himself; but one who prophesies edifies the church [promotes growth in spiritual wisdom, devotion, holiness, and joy].

Therefore, [unknown] tongues are [meant] for a [supernatural] sign, not to believers but to unbelievers [who might be receptive]; while prophecy [foretelling the future, speaking a new message from God to the people] is not for unbelievers but for believers.
