The stone [which] the builders rejected Has become the chief cornerstone. Psalms 118:22 (NKJV)
The builders are everyone who think they can be and do right and live in their own wisdom and strength apart from God. The stone they rejected but became the chief cornerstone is Jesus Christ who is God’s Way of being and doing right. In seeking to be and do right in our own wisdom and strength we automatically reject God’s way of being and doing right.The reason people despise and reject God’s way is because from a human point of view it looks foolish and weak – 1Corinthians 1:18-23. For example God provides salvation and right standing with Him through the suffering and death of His Son Jesus. Man does not contribute anything, he only believes and receives. This is hard to take in by people who have been brought up to rely on their own efforts and merit. God uses what’s foolish and weak in man’s eyes in order to destroy what man boasts in so that no one boasts in themselves before God – 1Corinthians 1:27-29.
