Love–as Christ expressed love–is two faceted. Part of love comes from the heart (mind) in the form of devotion, desire, longing, concern, empathy , etc. Another part of love is action–self-sacrifice, working for sanctification, nourishing, honoring, etc.
Love is both motive and vehicle for faith and obedience.
For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known. So now faith, hope, and love abide, these three; but the greatest of these is love.
