How do we know that God establishes Zion?

The sermon clearly states that 'the Highest Himself shall establish her,' denoting that the establishment of Zion is entirely God's work. This affirmation underlines the sovereignty of God in salvation and His eternal purposes. For instance, the concept that God has chosen and called His people before the foundation of the world emphasizes that salvation and the church's foundation depend solely on His grace. Only God, through His infinite wisdom and merciful councils, can shape and secure His people in this eternal covenant of grace, ensuring their place in His kingdom.
