Why is understanding the phrase 'the Lord hath need of him' important for Christians?

This phrase from the sermon reveals the deep theological truth that God's plans are fulfilled through His chosen people. While God does not need anything from us in the sense of lack or dependence, He accomplishes His purposes through His elect, forming the body of Christ. 1 Corinthians 12:12-27 highlights that each member is vital to the body’s health. The phrase encourages believers that they are integral to God’s redemptive work; it also underscores the privilege and responsibility associated with being part of His sovereign plan. Understanding this helps Christians find meaning in their faith and work, recognizing that they are not merely passive recipients of grace but active participants in God's unfolding story of salvation.
