One may have struggles to have peace in the present world. There are battles and trials and worries. There are complaints and weariness. Then there is God's peace. All else in faith has vanished away to give way to God's peace.
"To be spiritually minded is life and peace." Romans 8: 6 KJV
Think on this:
God's peace has released my mind. I am no longer subjected to thinking of a world's peace, His peace has freed and unchained my life.
