Mal 3:6 I the LORD do not change.
Consider the North star or a lighthouse. Both are used in navigation as an unchanging point of reference. They are also both used in the dark.
Like a lighthouse or a star, the LORD should be our unchanging point of reference when navigating in the dark.
In Isaiah 50:10 we read:
"Let him who walks in the dark, who has no light, trust in the name of the LORD and rely on His God."
If, in the dark, we take our eyes off of our LORD, then we have turned away from the light. With no point of reference, we will get lost in the darkness, we will stumble and become disoriented and frightened.
If, however, our eyes are fixed on the Light as we trust in our LORD, we will keep heading in the right direction. Keep your eyes on the unchanging Light for He is trustworthy. Keep your eyes fixed on the Light and He will steer you through the darkness.
