Isa 26:3 You will keep him in perfect peace, whose mind is stayed on You: because he trusts in You
Perfect peace. Oh what a marvelous state. Who among us would not revel in “perfect peace.” Yet here is a promise from the Living God to His people, with two conditions. Conditions you say? Yes, indeed. And the two here stated are firstly, “whose mind is stayed on You.” Seek you first the Kingdom of God and His righteousness. See Him in all His glory. See Him high and lifted up above your circumstances. Was He not lifted up upon a cross for you? See Him high and lifted up above every storm. Above every set of circumstances, above every ailment and serious infirmity. For when you see Him as such and glorify Him as such does not the Spirit of Christ rest upon you? When the world and even your own mind and body attempts to wrestle you away from a singular focus on Him, shall we not resist this?
Secondly, trust in the Lord your God. Trust Him on the mountain, trust Him in the valley, trust Him when your enemies are all around and to your aid He rallies. Trust Him in the morning when the sun rises in the sky, trust Him on your sickbed when men say that you will die. Trust Him in the noonday when the sun is overhead, trust Him for your sustenance and for your daily bread. Trust Him as the sun goes down and in the twilight hour, for even in the darkness He is your light and He’s your power. To keep your eyes on Him and to trust Him in all things is to walk through the door of perfect peace. Won’t you go in brothers and sisters? Look up unto the heavens and revel in the glory of God and you shall revel in His peace, His perfect peace.
