He that turneth away his ear from hearing the Law. He who refuses to hearken to and to practise the dictates of the Divine law (comp Proverbs 1:20. Even his prayer shall be abomination (comp. Proverbs 15:8, and note there).
"God heareth not sinners" (John 9:31). Such a man's prayer, if he does pray, is not hearty and sincere, and therefore, lacks the element which alone can make it acceptable. He will not resolve to forsake his favourite sin, even while paying outward worship to the God whoso Law he breaks: what wonder that the prophet so sternly denounces such offenders (Isaiah 1:11.
etc.), and the psalmist cries with terrible rigour, "When he shall be judged, let him be condemned; and let his prayer become sin" (Psalms 109:7)? St. Gregory ('Moral.,' 10.27), "Our heart blames us in offering up our prayers, when it calls to mind that it is set in opposition to the precepts of him whom it implores, and the prayer becomes abomination, when there is a 'turning away' from the control of the Law; in that wrily it is meet that a man should be a stranger to the favours of him to whose bidding he will not be subject."
And again (ibid; 18.9, 10), "If that which he bids we do, that which we ask we shall obtain. For with God both these two do of necessity match with one another exactly, that practice should be sustained by prayer, and prayer by practice" (Oxford transl.
).
