Anxiety
Peace that guards
“Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.”
Peace here is not the absence of trouble but a guard posted at the door of your heart. Prayer is how the guard is invited in.
One practice
Turn one worry into one sentence of prayer, then breathe out.
Prayer
Lord, my thoughts are loud. Post Your peace at the door of my heart tonight.
