two shells

If God’s peace is in our hearts, we carry it with us, and it can be given to those around us, not by our own will or virtue, but by the Holy Spirit working through us. We cannot give what we do not have, but if the spirit blows through the dark clouds and enters our hearts, we can be used as vehicles of peace, and our own peace will be thereby deepened. The more peace we give away, the more we have.
