Love is the overflow of joy in God! It is not duty for duty's sake, or right for right's sake. It is not a resolute abandoning of one's own good with a view solely to the good of the other person. It is first a deeply satisfying experience of the fullness of God's grace, and then a doubly satisfying experience of sharing that grace with another person.
Love fasts when it can, and as much as it can. It leads to all the ordinances of God, and employs itself in all the outward works whereof it is capable. It flies, as it were, like Elijah over the plain, to find God upon his holy mountain.
