“Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee” (Isaiah 26:3).
Perfect peace is rendered in the Hebrew, “Shalom, shalom.” God’s people are kept in “Shalom, shalom” when they have their minds stayed on the Lord and trust in Him. Note three places where peace is promised to the believer: “Therefore being justified by faith, we have peace with God through our Lord Jesus Christ” (Romans 5:1). The believer has what is called “peace with God.” We were sinners (guilty) before the law court of God, but now we are justified (not guilty!); therefore, now that the sin question has been settled, we no longer fear to stand before God. We are “in Christ” (Romans 8:1; 16:7; I Corinthians 1:2; etc.). Thus, His presence produces continual peace before a holy God. “And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus” (Philippians 4:7). The “peace of God” mentioned in this text is given to quiet the state of our heart because of circumstances. So many things can seemingly take away our peace. We believers are ever bombarded with trials, sufferings, and tribulations that the devil likes to use to disturb and discourage us. But the Lord has promised peace in our hearts and minds. The Lord desires to give peace in the emotional part of us (the heart), and also in the intellectual part of us (the mind). He will keep, that is guard (military term) our hearts and minds. “Peace I leave with you, my peace I give unto you” (John 14:27). Personal, practical peace comes from the Prince of Peace, the Lord Jesus Christ. We don’t have to work up peace; it comes from Christ, directly, and is the fruit of the Spirit. Therefore, “let not your heart be troubled, neither let it be afraid” (John 14:27). NPS
