The Christian doctrine shows man that the essence of his soul is love—that his happiness depends not on loving this or that object, but on loving the principle of the whole—God, whom he recognizes within himself as love, and therefore he loves all things and all men.

Context

“With the Christian conception of life, love is not a necessity and is confined to no object; it is the essential faculty of the human soul. Man loves not because it is his interest to love this or that, but because love is the essence of his soul, because he cannot but love.
The Christian doctrine shows man that the essence of his soul is love—that his happiness depends not on loving this or that object, but on loving the principle of the whole—God, whom he recognizes within himself as love, and therefore he loves all things and all men. In this is the fundamental difference between the Christian doctrine and the doctrine of the Positivists, and all the theorizers about universal brotherhood on non-Christian principles.
Such are the two principal misunderstandings relating to the Christian religion, from which the greater number of false reasonings about it proceed.” source
