Another good one from GotQuestions?
Answer: 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.
The proverb also indicates the need for constant fellowship with one another. Man was not made to be alone, for did not the Lord God say this, even before the Fall (Genesis 2:18)? How much more, then, after the Fall of Man, do we need to come together with our brothers and sisters in Christ for seasons of fellowship and prayer? Clearly, this was recognized by the saints of the early church (Acts 2:42–47), who “devoted themselves” to teaching, fellowship, communion, and prayer, all corporate activities that provided opportunities for sharpening one another.
There are two points to make about the above proverb. First, the meeting of two together in the Lord’s name will always guarantee blessing. It is a means of grace that the Lord Himself promised—where two or more are gathered in His name, there He is among them (Matthew 18:20). Also, we see a similar meaning in Malachi, for those who feared the Lord talked with each other, and the Lord listened and heard (Malachi 3:16). When we sharpen one another in real Christian fellowship, the Lord bends an ear from heaven and is pleased. Not one word about Him which brings Him glory escapes His notice.
