"Thus the nations shall know that I am the Lord, says the Lord God, when in their sight I prove my holiness through you." --Ezekiel 36:23

God will prove his holiness through us?!? We'd better get moving on the path to sainthood! which is what we are all called to- a vocation of love, which is a vocation of participating in the eternal exchange of love which is God. Through being open and receptive to God, even in pain, is how we attain holiness.
