What does it mean that the church is dependent on God's grace?

The dependency of the church on God's grace is fundamental to its existence. While the church is called to preach the gospel and honor the Lord, it recognizes that no meaningful spiritual work can occur apart from God's empowerment. The oil flowing from the olive trees in Zechariah's vision represents the Holy Spirit, highlighting that spiritual sustenance and enlightenment come solely from God. This underscores the Reformed understanding that salvation and perseverance in faith are based on grace alone, ensuring that all aspects of the church's life and ministry rely upon divine intervention. Without God's sustaining grace, the church cannot shine as a light in the world.
