“Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?”
King James Version (KJV)
14:6 Revelation - Of some gospel mystery. Knowledge - Explaining the ancient types and prophecies. Prophecy - Foretelling some future event. Doctrine - To regulate your tempers and lives. Perhaps this may be the sense of these obscure words.
1Co 14:6 What shall I profit you? The gift of tongues, exercised to the church, cannot profit unless it does one of four things named: A revelation. The inspired utterance of him who "prophesies". Knowledge. The gift of teaching the inspired truths of the Scriptures, or those revealed by the prophets.
