Your faith must be immovable as the rock, must weather every storm and survive every calamity. Suffer not the denunciations of the foolish and the calumnies of the clergy to afflict you, or to turn you from your purpose. For you are called to partake of the celestial banquet prepared for you in the immortal Realm. You are the first to leave the House of God, and to suffer for His sake. If you be slain in His path, remember that great will be your reward, and goodly the gift which will be bestowed upon you. Mullá `Alí was soon on his way to `Iráq. Then the Báb called together the other sixteen disciples and spoke to them, adjuring them to go out into the world and serve their God in the light of the faith given to them: O My beloved friends!
