“The stone the builders rejected has become the capstone" (Psalm 118:22).
The image comes from the ancient quarries where highly-trained stonemasons carefully chose the stones used in construction. No stone was more important than the cornerstone because the integrity of the whole structure depended on the cornerstone containing exactly the right lines. If the cornerstone was not exactly right, the entire building would be out of line. For that reason, builders inspected many stones, rejecting each one until they found the one they wanted. Rejected stones might be used in other parts of the building, but they would never become the cornerstone or the capstone (the first and last stones put in place).
When Peter preached to the Jewish leaders in Acts 4:8–12, he quoted Psalm 118:22 to show that Jesus is the rejected stone whom God made to be the cornerstone of salvation. They (the Jewish leaders) rejected him, but God not only accepted him but put him in the position of highest honor.
Peter pressed the point home with this powerful conclusion: “Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved" (Acts 4:12). These words are utterly exclusive. There is no other hope, no other way, and no other name than the name of Jesus. If we would be saved, we must come God’s way or we won’t come at all.
Do not be like the builders who rejected God’s Stone of salvation! Do not reject Jesus Christ. Do not stumble over this rejected stone. The very stone the builders rejected has become the head of the corner. May God open your eyes to see Jesus as he really is—the Cornerstone of eternal salvation.
