Let him never cease from prayer, who has once begun to pray, even though his life is ever so bad. For prayer is the only way to amend one's life and without prayer it will never be mended. Let him not be tempted of the devil, as I was, to give up prayer on account of one's unworthiness. Let such a one rather believe that if he will only repent and pray, our Lord will still hear and answer.
Teresa of AvilaAll the troubles of the Church, all the evils in the world, flow from this source: that men do not by clear and sound knowledge and serious consideration penetrate into the truths of Sacred Scripture.
