"Nothing whatever can, in this Day, inflict a greater harm upon this Cause than dissension and strife, contention, estrangement and apathy, among the loved ones of God."

"Show forbearance and benevolence and love to one another. Should any one among you be incapable of grasping a certain truth, or be striving to comprehend it, show forth, when conversing with him, a spirit of extreme kindliness and good-will. Help him to see and recognize the truth, without esteeming yourself to be, in the least, superior to him, or to be possessed of greater endowments.

The whole duty of man in this Day is to attain that share of the flood of grace which God poureth forth for him. Let none, therefore, consider the largeness or smallness of the receptacle. The portion of some might lie in the palm of a man’s hand, the portion of others might fill a cup, and of others even a gallon-measure.

Every eye, in this Day, should seek what will best promote the Cause of God. He, Who is the Eternal Truth, beareth Me witness! Nothing whatever can, in this Day, inflict a greater harm upon this Cause than dissension and strife, contention, estrangement and apathy, among the loved ones of God. Flee them, through the power of God and His sovereign aid, and strive ye to knit together the hearts of men, in His Name, the Unifier, the All-Knowing, the All-Wise."
