What does the Bible say about the government of God's grace?

According to Isaiah 9:6-7, the government of God's grace is about the sovereignty of Christ as our Savior. This passage illustrates that the leadership and administration of salvation are all placed upon His shoulders. Christ is described as 'Wonderful, Counselor, the Mighty God, the Everlasting Father, the Prince of Peace,' indicating His divine authority and the peace He brings between God and His people through His redemptive work. It is not contingent on human actions but fully relies on the grace and sovereignty of Christ, ensuring that salvation is secured without failure.
