Romans 8:6 says,
The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace.
Look at the last word. Peace is one of the most underrated things we rarely ask for in prayer. Do we realize that with PEACE, nothing else matters? So when we are in our own cultural world of rushing, anxiety, stress, task lists etc that we are OPPOSITE of peace. Yet when we surrender to the spirit (and live in prayer) we then have peace. And peace makes very worry and fear melt away. Peace comes from faith and confidence in the Lord.
