Read verses 4-5
Q: What greater thing are the terms “cornerstone”, “tent peg” and “bow of battle” describing?
A: They are three aspects of the Messiah.
Q: What is the meaning of “the cornerstone”?
A: There are two prominent scriptural uses, one as the most important foundational stone in the temple foundation, the other as the capstone which completes the house of God. In either case, it is the representation of Christ upon whom everything else is built or with whom God’s house is held together and completed.
The stone which the builders rejected
Has become the chief corner stone.
— Psalm 118:22
So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord,
— Ephesians 2:19-21
Q: What is the meaning of “the tent peg”?
A: This is attached to a tent’s ropes and hammered into the ground so as keep the tent erect. Whereas the cornerstone represents building upon Christ the Word, the peg mimics the spiritual stature resulting from being tied to Christ the Word.
Q: What is the meaning of “the bow of battle”?
A: In the ancient world this is a primary symbol of authority and power, distinctly identified “of battle” so as to distinguish between hunting for one’s daily needs versus engaging the enemy.
He has also prepared for Himself deadly weapons;
He makes His arrows fiery shafts.
— Psalm 7:13
Point: These three metaphors for aspects of the Messiah’s working are also the greater responsibilities which accompany the leadership of God’s people to provide the foundation of God’s Word, to keep the people erect spiritually by their compliance with God’s Word, and thus be able to be victorious over all who come against them. Leadership without the Word in reality is worse than no leadership because it is actually false leadership.
Q: What might be significant about ultimately becoming “mighty men” in v.5?
A: This is a term which referred specifically to those following David who were not just physically mighty, but equally spiritually mighty as well. The heavenly attributes work in the visible, earthly situations as well.
Application: Both the working of the Word in the Old Testament as well as the New produce the same result: transformation into the likeness of the Messiah.
But you did not learn Christ in this way, if indeed you have heard Him and have been taught in Him, just as truth is in Jesus, that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit, and that you be renewed in the spirit of your mind, and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.
— Ephesians 4:20-24
But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as from the Lord, the Spirit.
— 2 Corinthians 3:18
