O ye beloved of God, know that steadfastness and firmness in this new and wonderful Covenant is indeed the spirit that quickeneth the hearts which are overflowing with the love of the Glorious Lord; verily, it is the power which penetrates into the hearts of the people of the world! Your Lord hath assuredly promised His servants who are firm and steadfast to render them victorious at all times, to exalt their word, propagate their power, diffuse their lights, strengthen their hearts, elevate their banners, assist their hosts, brighten their stars, increase the abundance of the showers of mercy upon them, and enable the brave lions (or teachers) to conquer.
Hasten, hasten, O ye firm believers! Hasten, hasten, O ye steadfast! Abandon the heedless, set aside every ignorant, take hold of the strong rope, be firm in this Great Cause, draw light from this Evident Light, be patient and be steadfast in this wise Religion! Ye shall see the hosts of inspiration descending successively from the Supreme World, the procession of attraction falling incessantly from the heights of heaven, the abundance of the Kingdom of Abha outpouring continually and the teachings of God penetrating with the utmost power, while the heedless are indeed in evident loss.
