1 Corinthians 1:5

By "speech" (NASB) or "speaking" (NIV; Gr. logos) the apostle meant eloquence, the ability to express their "knowledge" (Gr. gnosis) fluently and effectively. As we shall see, knowledge and eloquence were two things the Corinthians valued very highly. These characteristics appear by their usage in this letter and in 2 Corinthians to have been common buzzwords in Corinth. Logos occurs 26 times in 1 and 2 Corinthians compared to 58 times in Paul’s other epistles, and gnosis appears 16 times in these two epistles but only seven times in all of Paul’s other writings. Paul had to put these gifts in their proper place among the other gifts. Nevertheless they were great gifts, and Paul was thankful that God had given them to the Corinthians.
