Philippians 4:6-7 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
There are three basic types of peace mentioned in the Bible. The peace of God that comes with salvation, Rom. 5:1. The peace of God that comes through total surrender to God in all things, Phil. 4:6-7; John 14:1, 27. The peace on earth that will come when Jesus Christ comes back to reign in glory and power, Isa. 2:1-4.
The peace that comes with total surrender is the peace of God in times of trouble, the peace that overwhelms our worries and helps us rest in the will of the Lord even when we can’t see what lies ahead.
The key to experiencing the peace of God which passes all understanding --- which keeps our hearts and minds through Christ Jesus --- lies in a thankful heart and a song of praise.
