O thou who art attracted to the Kingdom of God!
Thy detailed letter was received. Its perusal produced the utmost happiness, for it evidenced the fact that thou hast attained to the knowledge of the reality of tests; that tests endured in the path of God are conducive to confirmation; nay, rather, they are heavenly powers and the bounties of the Realm of Might. But to weak believers tests are trials and examination, for, on account of the weakness of their faith and assurance they fall into difficulties and vicissitudes. However, to those souls who are firm and steadfast, tests are the greatest favors.
Consider thou that at the time of an examination in sciences and arts, the dull and lazy pupil finds himself in calamity. But to the intelligent and sagacious student examination in learning produces honor and infinite happiness. Alloyed gold, subjected to the fire, portrays its baseness, while the intensity of the flame enhances the beauty of pure gold.
Therefore, tests to the weak souls are calamity and to the veiled ones the cause of their disgrace and humiliation. The point is This, that in the path of Truth every difficulty is made plain and every trial is the matchless bounty. Therefore, the believers of God and the maid servants of the Merciful must not relax during trial and no disaster must deter their service in the Cause of God. …
