What is it that could have induced them to reconcile themselves to these grievous trials, and to refuse to put forth a hand to repel them?
What could have caused such resignation and serenity?
The true cause is to be found in the band which the Pen of Glory hath, day and night, chosen to impose, and in Our assumption of the reins of authority, through the power and might of Him Who is the Lord of all mankind .-- Epistle to the Son of the Wolf, pp.

74-75.
The soundness of Baha'u'llah's nonresistance policy has already been proved by results.

For every believer martyred in Persia, the Baha'i faith has received a hundred new believers into its fold, and the glad and dauntless way in which these martyrs cast the crowns of their lives at the feet of their Lord has furnished to the world the clearest proof that they had found a new life for which death has no terrors, a life of ineffable fullness and joy, compared with which the pleasures of earth are but as dust in the balance, and the most fiendish physical tortures but trifles light as air.
Righteous Warfare Although Baha'u'llah, like Christ, counsels His follows as individuals and as a religious body to adopt an attitude of nonresistance and forgiveness toward their enemies, He teaches that it is the duty of the community to prevent injustice and oppression.

If individuals are persecuted and injured it is wrong for a community to allow pillage and murder to continue unchecked within its borders.

It is the duty of a good government to prevent wrongdoing and to punish offenders.( 32) So also with the community of nations.
