Even the robin loves and cares for its young. Yet, all this does not compare with, cannot reach up to the love in that highest sense which Scripture defines as the bond of perfectness. For and this, too, must be emphasized, love is the bond of perfectness. It is a spiritual bond that is established and functions only in the sphere of moral perfection. The wicked do not love, whatever other bond there may be between them.
Love is the bond of perfection.
It is the attraction of person to person in the sphere of the light. It is the longing of spirit for spirit, a seeking and finding of each other, a living into each other's life, a giving wholly of each to the other, a complete possession of the other, a seeking of each other's good, the will to please each other, a perfect delight in each other - all in the sphere of ethical perfection. Herein is love. . . Between them love is, and must needs be, bilateral, two-sided, mutual. The love of the one is incapable of kindling love in the other.
