The local church is a divine institution established by God Himself, not a human invention. Founded by Christ as stated in Matthew 16:18, the church serves as both the foundation and support for truth in a relativistic world. It provides essential spiritual growth through leaders who equip believers for ministry and service. Christians need consistent, accountable connections to a church body to thrive spiritually, much like trees need to be deeply planted rather than merely potted. The ultimate purpose of the church is to bring glory to God through believers serving, forgiving, and loving one another.
