Every believer is transformed and called by the Lord to be an influence for His gospel throughout the world.
Commentary from the MacArthur study Bible, notes for 2 Corinthians 2:14.
To speak with grace is to speak what is spiritual, wholesome, fitting, kind, sensitive, purposeful, complimentary, gentle, truthful, loving, and thoughtful. Just as salt not only flavors, but prevents corruption, the Christian’s speech should act not only as a blessing to others, but as a purifying influence within the decaying society of the world.
Commentary from the MacArthur study Bible, notes for Colossians 4:6.
