How to develop idea from Psalm 27:1

Psalm 27: 1 say‘s: “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?” What is the idea that this verse tries to state? According to the 2012 Watchtower magazine entitled: “Of Whom Shall I Be in Dread?” states: “While fear can exert a weakening influence, the feeling of dread is even more severe. But no underlying dread should agitate one who fears Jehovah. When we make Jehovah our stronghold, we “will reside in security and be undisturbed from dread of calamity.” The metaphor “Jehovah is my light” draws attention to the fact that Jehovah frees us from ignorance and spiritual darkness.
