The only real difference that exists between people is that they are at various stages of development. Some are imperfect—these must be brought to perfection. Some are asleep—they must be awakened; some are negligent—they must be roused; but one and all are the children of God. Love them all with your whole heart; no one is a stranger to the other, all are friends.
- ‘Abdu’l-Baha (From a talk; ‘Paris Talks: Addresses given by ‘Abdu’l-Bahá in Paris in 1911-1912’)
