7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. 
The Lord’s direct answer to the prayer replaces any anxiety.
Things that we cannot comprehend or understand can be peaceful to those who are
in Christ. God’s peace acts as a military guard, setting up defense over our
hearts, always keeping us focused on the truth of God, in the midst of
threating circumstances. Know this peace, and cherish it forever knowing that
God goes before you and stands guard over you no matter what trials we face.
