From Paul Tripp’s What Did You Expect?:

…love is fundamentally deeper and more active than some warm, romantic feeling of affection toward someone to whom you are attracted. It is not some generalized response of happiness when you are with this particular person. No, love is a specific commitment of the heart to a specific person that causes you to give yourself to a specific lifestyle of care that requires you to be willing to make sacrifices that have that person’s good in view. Love is never general, and it never remains in the realm of feelings. Love desires, love thinks, love chooses, love decides, love acts, and love speaks in an ongoing, day-by-day commitment to the welfare of another. Real love is concrete, specific, and active.
