"The Lord is my light and my salvation; whom shall I fear? The Lord is the stronghold of my life; of whom shall I be afraid? Psalm 27:1
David writes with supreme confidence of the goodness of the Lord and His willingness to help those who trust in Him. He utilizes three words to compare the protection of the Lord.
David sees the Lord as his light. In a world filled with darkness, our God is our light. In the darkness, it is difficult to move. Where there is no light, we cannot see the dangers that are lurking. For these reasons and many others, David takes heart that the Lord is his light.
