◄ Symbolism of "precious cornerstone"? ►

The Verse in Focus: Isaiah 28:16

“Therefore the Lord GOD says:

‘See, I lay a stone in Zion, a tested stone,

a precious cornerstone, a sure foundation;

the one who believes will never be shaken.’”

Key Term: Cornerstone in Ancient Building

• Laid first at the foundation’s corner

• Determines the position, angle, and integrity of every other stone

• Bears the initial weight and ties two walls into one unified structure

In short, everything in the building aligns to, leans on, and is secured by this single stone.

New Testament Echoes—Identifying the Stone

• Romans 9:33; 1 Peter 2:6—quote Isaiah 28:16 directly and apply it to Jesus Christ

• Ephesians 2:20—“Christ Jesus Himself being the chief cornerstone”

• Acts 4:11—Jesus is “the stone you builders rejected, which has become the cornerstone”

The inspired writers leave no doubt: the “precious cornerstone” is Christ.

What the Cornerstone Symbolizes in Christian Doctrine

1. Foundation of Salvation

• Only those resting on Christ stand secure (1 Corinthians 3:11).

• Belief in Him keeps believers from ever being “shaken.”

2. Tested and Trustworthy Character

• “A tested stone” means Christ has been proven sinless (Hebrews 4:15).

• His faithfulness under trial assures us He can carry the weight of our lives.

3. Unifying Center for God’s People

• Jew and Gentile are “fitted together” around Him into one holy temple (Ephesians 2:21–22).

• The gospel demolishes dividing walls by anchoring everyone to the same Cornerstone.

4. Plumb Line of Truth

• As walls align to the cornerstone, doctrine and conduct align to Christ’s teaching (John 14:6).

• Any belief that deviates from Him shows immediate crookedness.

5. Stone of Division and Judgment

• For believers, He is “precious” (1 Peter 2:7); for rejecters, He is “a stone of stumbling” (Isaiah 8:14).

• Our eternal destiny pivots on whether we trust or trip over this Cornerstone.

Practical Takeaways

• Build your theology, identity, and daily choices on Christ alone; everything else will shift.

• Measure every new idea against His Word; if it won’t square with the Cornerstone, discard it.

• Enjoy the security promised: “the one who believes will never be shaken.”
