Prayer of St. Francis de Sales, Be at Peace:
Do not look forward in fear to the changes of life; rather look to them with full hope as they arise. God, whose very own you are, will deliver you from out of them. He has kept you hitherto, and He will lead you safely through all things; and when you cannot stand it, God will bury you in his arms. Do not look forward to what may happen tomorrow; the same everlasting Father who cares for you today will take care of you tomorrow and every day. Either He will shield you from suffering, or He will give you unfailing strength to bear it. Be at peace, then, and put aside all anxious thoughts and imaginations, and say continually:
"The Lord is my strength and my shield; my heart has trusted in Him and I am helped. He is not only with me but in me and I in Him."
Amen.
