"Peace I leave with you; My peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be fearful." (John 14:27) The Spirit of God, the Helper, dwells with us. He is sovereign over all and He loves us, so how could we worry about anything in this world? The peace of God should rest on those who trust Him.
