1 Corinthians 14:39-40, Covet to Prophesy
The gift of prophecy is highlighted here to be useful for the strengthening of the faith of the saints. When the Word of God is preached and taught, when doctrine, reproof, correction, instruction in righteousness is meted out, God’s people grow in spiritual maturity. This is useful. The people of God are therefore encouraged to keep up and keep on hearing the sound preaching and teaching of God’s Word.
