The second of these spiritual standards which apply to the possessor of knowledge is that he should be the defender of his faith. It is obvious that these holy words do not refer exclusively to searching out the implications of the Law, observing the forms of worship, avoiding greater and lesser sins, practicing the religious ordinances, and by all these methods, protecting the Faith. They mean rather that the whole population should be protected in every way; that every effort should be exerted to adopt a combination of all possible measures to raise up the Word of God, increase the number of believers, promote the Faith of God and exalt it and make it victorious over other religions.
