The heart has to be purified. Man must acquire spiritual chastity; that is, sincerity, honesty, selflessness, humility, goodness, forbearance, sacrifice. This is how man becomes akin to God and how divine Grace comes to dwell in him. When someone has physical chastity but lacks spiritual chastity, God cannot dwell in him because he harbours cunning, pride, evil, and so forth. Then this person’s life is a sham; this is where you must begin your struggle: acquiring spiritual chastity, spiritual purity…, it is the mortal sins which pollute our Baptism, and that’s when divine Grace is distanced from us. Of course, God’s Grace does not abandon man, even as our Guardian Angel does not abandon us.
