"As this human world is one household, why should its members be occupied with animosity and contention?"

"The second principle or teaching of Bahá’u’lláh is the proclamation of the oneness of the world of humanity—that all are servants of God and belong to one family; that God has created all and, therefore, His bestowals are universal; and that His providence, training, sustenance and loving-kindness surround all mankind.

This is the divine policy, and it is impossible for man to lay the foundation of a better plan and policy than that which God has instituted. Therefore, we must recognize and assist the purpose of the glorious Lord. Inasmuch as God is kind and loving to all, why should we be unkind? As this human world is one household, why should its members be occupied with animosity and contention? Therefore, humanity must be looked upon with the eye of equal estimate and in the same attitude of love. The noblest of men is he who serves humankind, and he is nearest the threshold of God who is the least of His servants. The glory and majesty of man are dependent upon his servitude to his fellow creatures and not upon the exercise of hostility and hatred."
