Love is the fundamental principle of God’s purpose for man, and He has commanded us to love each other even as He loves us. All these discords and disputes which we hear on all sides only tend to increase materiality.
The world for the most part is sunk in materialism, and the blessings of the Holy Spirit are ignored. There is so little real spiritual feeling, and the progress of the world is for the most part merely material. Men are becoming like unto beasts that perish, for we know that they have no spiritual feeling — they do not turn to God, they have no religion! These things belong to man alone, and if he is without them he is a prisoner of nature, and no whit better than an animal.
(Abdu’l-Baha, Paris Talks, p. 122)
