Adorn yourselves with the raiment of goodly deeds. He whose deeds attain unto God's good pleasure is assuredly of the people of Bahá and is remembered before His throne. Assist ye the Lord of all creation with works of righteousness, and also through wisdom and utterance. Thus, indeed, have ye been commanded in most of the Tablets by Him Who is the All-Merciful. He, truly, is cognizant of what I say. Let none contend with another, and let no soul slay another; this, verily, is that which was forbidden you in a Book that hath lain concealed within the Tabernacle of glory. What! Would ye kill him whom God hath quickened, whom He hath endowed with spirit through a breath from Him? Grievous then would be your trespass before His throne! Fear God, and lift not the hand of injustice and oppression to destroy what He hath Himself raised up; nay, walk ye in the way of God, the True One. No sooner did the hosts of true knowledge appear, bearing the standards of Divine utterance, than the tribes of the religions were put to flight, save only those who willed to drink from the stream of everlasting life in a Paradise created by the breath of the All-Glorious.
k160.
Promote ye the development of the cities of God and His countries, and glorify Him therein in the joyous accents of His well-favoured ones. In truth, the hearts of men are edified through the power of the tongue, even as houses and cities are built up by the hand and other means. We have assigned to every end a means for its accomplishment; avail yourselves thereof, and place your trust and confidence in God, the Omniscient, the All-Wise.
