How do we know that God is the ultimate authority?

The authority of God is firmly established in Scripture, specifically in His ability to declare the end from the beginning (Isaiah 46:10). This highlights that He not only knows future events but has ordained them according to His divine will. God's sovereignty is seen through His control over all creation and history, exercising authority over both good and evil as tools for His ultimate purpose (Proverbs 16:4). This sovereign governance assures us that nothing happens outside of His will, affirming His position as the ultimate authority in both salvation and judgment.
