“I bear witness, O my God, that Thou hast created me to know Thee and to worship Thee.”
"O people of the world! Build ye houses of worship throughout the lands in the name of Him Who is the Lord of all religions.

Then, with radiance and joy, celebrate therein the praise of your Lord, the Most Compassionate. Verily, by His remembrance the eye is cheered." -The Kitáb-i-Aqdas.
The institution of the Mashriqu’l-Adhkár, translated as “The Dawning Place of the Mention of God”, was ordained by Bahá’u’lláh Himself. It is a pivotal concept of Bahá’í community life, giving concrete expression to the unity of devotion and service. The Bahá’í House of Worship is dedicated to the praise of God. It forms the central edifice of the Mashriqu’l-Adhkár (the Dawning-place of the Praise of God), a complex which, as it unfolds in the future, will comprise in addition to the House of Worship a number of dependencies dedicated to social, humanitarian, educational, and scientific pursuits. ‘Abdu’l Bahá describes the Mashriqu’l-Adhkár as “one of the most vital institutions in the world,” and Shoghi Effendi indicates that it exemplifies in tangible form the integration of “Bahá’í worship and service.” Anticipating the future development of this institution, Shoghi Effendi envisages that the House of Worship and its dependencies “shall afford relief to the suffering, sustenance to the poor, shelter to the wayfarer, solace to the bereaved, and education to the ignorant.” In the future, Bahá’í Houses of Worship will be constructed in every town and village Temples are symbols of the reality and divinity of God -- the collective center of mankind. Consider how within a temple every race and people is seen and represented -- all in the presence of the Lord, covenanting together in a covenant of love and fellowship, all offering the same melody, prayer and supplication to God. Therefore, it is evident that the church is a collective center for mankind. For this reason there have been churches and temples in all the divine religions… (Abdu’l-Bahá, The Promulgation of Universal Peace).
