For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. Hebrews 4 :12
As we read this verse we think of the process of 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”
This verse shows us the need for fellowship with one another. We know that man was not made to be alone, for the Lord God say’s 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.
We know that the meeting of two people together in the Lord’s name will always bring blessing. The Lord Himself promised—where two or more are gathered in His name, there He is among them Matthew 18:20. Also, we also see 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.
“How good and pleasant it is when brothers live together in unity” Psalm 133:1. Therefore, as the author to the Hebrews says, “And let us consider how we may spur one another on towards love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching” Hebrews 10:24–25.
