You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you! (Isaiah 26:3 NLT)
In this declaration regarding our peace, the “You” referred to here, of course, is God Almighty. It’s saying that the God of the universe will keep all who trust in Him in perfect peace. The word keep here means to guard, maintain, protect, fulfill, and be faithful to the provision of peace in your life. Ephesians 2:14 tells us that Jesus is our peace and reminds us that peace is a person and not place or state of mind.
This scripture emphasizes that the price or condition of exchange for this peace is twofold. First, we are required to trust in God and His provision. God’s greatest gift to humanity is Jesus Christ as our Savior and Lord. The challenge is to trust and have faith that Jesus is indeed the personification of God’s loving provision for our need for redemption, peace, and reconciliation with Him. The second requirement stated is for us to focus or fix our thoughts on God.
Therefore by trusting in and keeping our thoughts directed toward God, He has pronounced that He will guard our peace. Keeping our mind on God requires us to remember Romans 8:37-39 (NLT) which says, No, despite all these things, overwhelming victory is ours through Christ, who loved us.And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons,neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love.No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord. For those who have received Jesus as Savior, there is nothing that can separate from God’s love.
God gives us further cause for confidence and focus for our thoughts in Hebrews 13:5-6 (NLT) that says, Don’t love money; be satisfied with what you have. For God has said, I will never fail you. I will never abandon you. So we can say with confidence, ‘The Lord is my helper, so I will have no fear. What can mere people do to me?’” Here we have a promise of devotion and faithfulness from God to us that should promote assurance and peace.
So, if we can have faith in the promises and intentions of God and maintain our thoughts, focused on His commitment to us, we can have peace that is provided and protected by God. (Adrian)
