In Luke 20 Jesus continues to teach and have encounters with the religious leaders. In vs. 17 Jesus asks his listeners, "…'Then what does this Scripture mean? "The stone that the builders rejected has now become the cornerstone."'" Jesus is quoting from Psalm 118:22. It's interesting that both the prophets Isaiah (28:16) and Zechariah (10:4) made references to this "cornerstone." In the New Testament Matthew (21:42) and Mark (12:10) both quote Jesus on this same saying. Luke again quotes it in Acts 4:11. The Apostles Paul (Ephesians 2:20) and especially Peter (1 Peter 2:4-7) reference this same "cornerstone".
So, if this Psalm is quoted by Jesus, Isaiah, Zechariah, Paul and Peter, among others, it must have been significant. So, we go back to Jesus' question - what does it mean?
Jesus is applying this Psalm to himself. He has just entered Jerusalem (on what we call Palm Sunday) and faces his last week on earth. He knows that on Friday he will be rejected by the religious leaders and the government and even the people. He knows he will hang on a cross and die. He understands that his rejection is only days ahead of him. Yet, in spite of this "rejection," he will become the cornerstone of life and faith.
The cornerstone was the first and most critical stone laid in building a structure, because everything else was built from it and on it. If the cornerstone was improperly placed, the whole structure would be in jeopardy. So, the cornerstone was crucial.
Jesus is quoting this scripture to tell his listeners that rejecting him doesn't change his importance and significance. God placed Jesus as the cornerstone of life and living, and apart from him, life will never be all it can be.
Many of the people in Jesus' time rejected him, and many still reject him. They fail to realize who he really is and why he is so important. Sometimes it's intentional, but often it's simply from neglect or laziness. Yet, the day will come when everyone will know who Jesus is. Paul wrote to the Philippians: "Therefore, God elevated him (Jesus) to the place of highest honor and gave him the name above all other names, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." (2:9-11)
Jesus is Lord and Master, whether we realize it or acknowledge it. But those who fail to acknowledge him will find that they built their life on something that will never support life now and for eternity. This isn't what Jesus wants, nor is it what his church wants. So, am I building my life upon the cornerstone? Have I chosen a cornerstone that is sure and true and strong? And what about those around us? Our goal and mission is to lead everyday people to build their lives on this cornerstone, this rock, that will withstand all the floods of life and remain standing into eternity. With so much at stake, how can we do anything less?
