It is easy to be a slave to the letter, and difficult to enter into the spirit easy to obey a number of outward rules, difficult to enter intelligently and self-sacrificingly into the will of God easy to entangle the soul in a network of petty observances, difficult to yield the obedience of an enlightened heart easy to be haughtily exclusive, difficult to be humbly spiritual easy to be an ascetic or a formalist, difficult to be pure, and loving, and wise, and free easy to be a Pharisee, difficult to be a disciple very easy to embrace a self-satisfying and sanctimonious system of rabbinical observances, very difficult to love God with all the heart, and all the might, and all the soul, and all the strength.
