The eventual outcome of Faith is to bring death unto ones reasoning mind, all as one is established by Faith in the Mind of Christ.
In this process there is indeed “War before Peace” for ones reasoning mind is hostile to the Mind of Christ. It is as one hears and obeys the voice of God that Faith is exercised, from this Faith increases, and slowly the reasoning mind becomes less and less of ones means of understanding.
This all in the Wisdom of God is for ones transformation from death (man’s reasoning) into Life (God’s Word). In God’s timing this yields what God and man have come into agreement upon, man’s Salvation and birthing into God’s realm of Life.
Two cannot walk together unless they agree, and Salvation through Faith is the Way God and man fully come into agreement. This yields the precious Peace that man so desperately desires all in and by the workmanship of God’s hands, transforming man into God’s likeness and image.
