Be watchful, stand firm in the faith, act like men, be strong.
The phrase “iron sharpens iron” is found in Proverbs 27:17: “As iron sharpens iron, so one man sharpens another.” There is mutual benefit in the rubbing of two iron blades together; the edges become sharper, making the knives more efficient in their task to cut and slice. Likewise, the Word of God is a “double-edged sword” (Hebrews 4:12), and it is with this that we are to sharpen one another—in times of meeting, fellowship, or any other interaction.
