All men have been called into being for the betterment of
the world. It behoveth every soul to arise and serve his brethren for the sake
of God. Should a brother of his embrace the truth, he should rejoice that the
latter hath attained unto everlasting favour. Otherwise he should implore God
to guide him without manifesting the least trace of animosity or ill-feeling
towards him. The reins of command are in the grasp of God. He doeth what He
willeth and ordaineth as He pleaseth. He, verily, is the Almighty, the
All-Praised.

Bahá’u’lláh’s Responses to Mánikchí Sáhib and Other Writings’)
