Psalm 27:1 “The LORD is my light and my salvation; whom shall I fear? the LORD is the strength of my life; of whom shall I be afraid.” This is not a wishful thinking or mere confession to boost your faith; but a declaration based on the knowledge of God – who is The Light, and the source and power of divine illumination. King David who wrote this song, had once; without a weapon killed a lion and challenged a well-equipped army with a sling. He obviously knew what he was talking about. During good and bad times, Experiential knowledge makes a lot of difference. David was literarily saying; I know the LORD is my light. He is the source of strength and salvation needed for victory over adversity, and for protection in times of peace.
