It is the task of the Word of God to be our guardian, our moral and spiritual instructor. He teaches us to love freedom, to love our fellow man, to love and admire what is excellent, rather than merely what is effective or adequate. The Word will not permit us to get away with carelessness or mediocrity.
We all accept that there is special training for philosophers, for teachers, for athletes. Equally, for those who have chosen to major in holiness, there is special training in the Word. It involves, as does any serious training, almost every detail of life: walking, eating, resting, working, every part is disciplined and every part contributes to the goal of spiritual health and beauty.
Mind you, this training (unlike some of the others) does not put people under emotional or physical strain and tension. It is not a matter of driving oneself to the limit so much as allowing the Word to show us our weaknesses and moral flaws, and then bringing us the Savior’s own remedies, precisely gauged to meet every specific need.
(Clement of Alexandria [155-220 A.D.].)
