O ye friends, exert ye an effort! Every expenditure is in need of an income. This day, in the world of humanity, men are all the time expending, for war is nothing but the consumption of men and of wealth. At least engage ye in a deed of profit to the world of humanity that ye may partially compensate for that loss. Perchance, through the divine confirmations, ye may be assisted in promulgating amity and concord among men, in substituting love for enmity, in causing universal peace to result from universal war and in converting loss and rancour into profit and love. This wish will be realized through the power of the Kingdom.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha')
