Shells and red pebble

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, 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.”
