If Christians would train themselves to apply Psalm 16:8, it would give them the ability to overcome every fear and anxiety, and bring God’s power to bear on every situation in their lives: “I have set the LORD continually before me; because He is at my right hand, I will not be shaken.”
David is not saying here that he literally “placed” God before him, as if God were an idol who could be carried around. What he is saying is that by FAITH he remembered that God was always with him — mentally and spiritually “setting” Him before him at all times.
It is similar to what Brother Lawrence of France used to do, “Practicing the Presence” of God — acting as though God was always with him — because He is!! He was just a worker in the kitchen, but he did everything as for the Lord, as if God were right there with him. He would wash the dishes with the Lord, sweep the floor for Him — “practicing the presence” of God in whatever he did. That is what David is talking about here. He “set Yahweh continually before (him).”
But this word “SET” is a key. This is not just going to “happen.” It is up to us to practice it; we must SET God (by faith) continually before us, remembering that He is with us, and calling continually upon Him.
I have been in situations where I have quoted this verse, remembering that God was with me, and it gave me courage and strength. Unfortunately I’ve had other times when I have totally forgotten it! You & I have great power and peace available to us, every moment, if we will remember to put this truth into practice.
This is a great verse to memorize and apply: for ourselves, for our children, for anyone you know who needs comfort or courage or strength in any situation: “I have set the Lord continually before me; because He is at my right hand, I will not be shaken.”
