The Apostle Paul sought the believers in Corinth to focus on understanding the preaching and teaching of God’s Word for their spiritual strengthening and growth. The Word of God whether by revelation, knowledge imparted, of prophecy and of godly principles, is good for them when imbibed and assimilated for practical Christian living. But taking time in sessions where they would not understand what the speaker is speaking will not profit them. No doubt, it seemed quite impressive to see the speaker gesturing and speaking in a language unknown. It may be exciting to watch the display of such a gift for language.
