My admonition and exhortation to you is this: Be kind to all people, love humanity, consider all mankind as your relations and servants of the most high God. Strive day and night that animosity and contention may pass away from the hearts of men, that all religions shall become reconciled and the nations love each other so that no racial, religious or political prejudice may remain and the world of humanity behold God as the beginning and end of all existence. God has created all, and all return to God.
—‘Abdu’l-Bahá, The Promulgation of Universal Peace
