What does the Bible say about God as King?

In the Bible, God is described as the eternal King who is sovereign over all creation. As indicated in 1 Timothy 1:17, He is the 'King eternal, immortal, invisible, the only wise God.' This signifies not just His everlasting reign but also His purity and perfection. Unlike earthly rulers like Nebuchadnezzar, whose authority was temporary and flawed, God's dominion is eternal, and His laws reflect His holy nature. He commands with justice, seeking both to honor His righteousness and to save those He loves, demonstrating His mercy while maintaining His holiness.
