Do you know when people really become spiritual? It is when they become the slaves of God and are branded with His sign, which is the sign of the Cross, in token that they have given Him their freedom.
Teresa of AvilaLet 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.
