You will keep him in perfect peace,
Whose mind is stayed on You,
Because He trusts in You.
In times of trouble, in times of uncertainty and in times of despair, our fight or flight instinct kicks in. We either get angry or we shut down. The last feeling we naturally experience is... peace.
God's Word tells us that He will keep us in perfect peace. However, there are some stipulations. Our mind needs to focus on God rather than on our circumstances. To turn our eyes upon God rather than upon our circumstance is an act of faith. We are demonstrating our trust in God... no matter what. When we do so, He will keep us in perfect peace!
