What does the Bible say about being in darkness?

In Isaiah 50, we learn that the elect can experience seasons of darkness due to their own sins and disobedience to God's word. This darkness serves a purpose: it reminds believers of their need to cry out to the Lord for help. The Lord allows such experiences to foster a deepened reliance on Him, urging His people to trust in His name and stay upon Him. Notably, it's emphasized that God is sovereign over these experiences and uses them to renew our hearts and minds, guiding us to remain obedient and faithful despite trials.
