Our Lord and our Redeemer Jesus Christ in His living Gospel invited us to draw nigh in wisdom to the work of keeping His commandments, and to lay within ourselves the foundation of His discipline rightly, in order that the edifice of our life and character might mount up straightly. For he who knoweth not how to begin wisely the building of this tower which goeth up to heaven is not able to complete [it] or to bring it to the finish which is of wisdom. For knowledge and wisdom should order, and arrange, and work the beginning and end and founding [of the edifice], and whosoever beginneth thus is called a wise man by the word of our Redeemer, “Whosoever heareth these My words, and doeth them, is like unto a wise man who hath dug, and made deep, and set his building upon the rock: and the rain descended, and the rivers came, and the winds blew, and beat upon that house; and it fell not; for its foundations were laid upon the rock. But whosoever heareth and doeth not, is like unto a foolish man who set his building upon the sand, and even if feeble things beat upon his building they will sweep it away.” We are therefore bound by the word of our Teacher not to be constant listeners only to the Word of God but also constant doers. For the man who, though listening not, doeth, is better than the man who is constant in listening and empty of works, even as the word of the apostle Paul teacheth us, “For not the hearers of the law are righteous before God, but the doers of the law shall be justified: for if the Gentiles which have no law do by their own nature [the things] of the law, these, having no law, are a law unto themselves; and they show the work of the law written upon their hearts, and their conscience testifieth concerning them.” The hearing of the law is good, for it bringeth to the works thereof, and reading and meditation in the Scriptures, which purify our secret understanding from thoughts of evil things, are good, but if a man is constant in reading, and in hearing, and in the meditation of the word of God, and yet perfecteth not by his reading the labour of works, against this man hath the Spirit of God spoken by the hand of the blessed David, rebuking and reproving his wickedness, and restraining him from taking even the Holy Book into his polluted hands, saying, “For to the sinner speaketh God, What “hast thou [to do] with the books of My commandments, that thou hast taken My covenant in thy mouth? Thou hast hated My instruction, and thou hast cast My words behind thee” — Prologue.
