What does the Bible say about the division between light and darkness?

The Scriptures reveal that God, in His sovereign will, creates a clear division between light and darkness, analogous to the distinction between righteousness and unrighteousness. The essence of this division is seen in God's declaration that He creates darkness, evil, and sin through the mere removal or hiding of His presence. As Psalm 104:20 states, 'You make darkness, and it is night,' showcasing that darkness cannot exist apart from God’s decree (Isaiah 45:7). This division is a recurring theme throughout Scripture, demonstrating God's sovereign purpose in all creation and His authority over both light and darkness.
