Jesus used a lot of different images to describe His identity. He said He was the gate, the bread of life, the good shepherd, the son of man, etc. At one point, in order to demonstrate His role to His fellow Jews, He quoted Psalm 118:22, “The stone that the builders rejected has become the cornerstone.” The cornerstone is laid in order to give order and form to the whole building. Jesus was saying He is the foundation stone of the Kingdom of God. What a tragedy that many of His hearers and many of Paul’s hearers not only refused to align their lives with Christ as their cornerstone; instead, they tripped over it, ruining their souls.
