Christ is the fulfillment of all Messianic promises, and in Him you are eternally secure.
First Peter 2:6 is a paraphrase of Isaiah 28:16, which says, “Thus says the Lord God, ‘Behold, I am laying in Zion a stone, a tested stone, a costly cornerstone for the foundation, firmly placed. He who believes in it will not be disturbed.'” Isaiah was speaking of the Messiah—the coming Christ of God. Peter, writing under the inspiration of the Holy Spirit, applied Isaiah’s prophecy to Jesus.
In Isaiah’s prophecy, “Zion” refers to Jerusalem, which stands atop Mount Zion. Mount Zion is sometimes used figuratively in Scripture to refer to the New Covenant of grace, whereas Mount Sinai represents the Old Covenant of law. Isaiah was saying that God would establish the Messiah as the cornerstone of His New Covenant Temple, the church.
The analogy of believers as stones and Christ as the cornerstone would have great meaning for the Jewish people. When the Temple in Jerusalem was built, the stones used in its construction were selected, cut, and shaped in the stone quarry according to precise plans (1 Kings 6:7). Only then were they taken to the building site and set into place. The most important stone was the cornerstone, to which the various angles of the building had to conform.
God used a similar process to build His New Covenant Temple. Its stones (individual believers) are elect and shaped by the Holy Spirit to fit into God’s master plan for the church. Jesus Himself is the precious cornerstone, specially chosen and prepared by the Father to be the standard to which all others conform. He is the fulfillment of all Messianic promises, and the One in whom you can trust without fear of disappointment. That means you are secure in Him!
Live today in the confidence that Christ cannot fail. He will always accomplish His purposes.
