How do we know Christ's authority over the church is true?

The authority of Christ over the church is affirmed in multiple Scriptures, including Ephesians 1:21, where Paul tells us that He is far above all principality and power, showing that His dominion extends beyond this world. Furthermore, Colossians 1:18 declares that He is the beginning and the firstborn from the dead, underscoring His unique position and authority over life and death. His resurrection from the dead and ascension to the right hand of the Father confirm His role as the head. The truth of His authority is grounded in God’s sovereign plan, indicating that the church exists under His control and that He directs all things for the good of His elect.
