The ordinances of the endowment embody certain obligations on the part of the individual, such as covenant and promise to observe the law of strict virtue and chastity, to be charitable, benevolent, tolerant and pure; to devote both talent and material means to the spread of truth and the uplifting of the race; to maintain devotion to the cause of truth; and to seek in every way to contribute to the great preparation that the earth may be made ready to receive her King,—the Lord Jesus Christ. With the taking of each covenant and the assuming of each obligation a promised blessing is pronounced, contingent upon the faithful observance of the conditions.
