We can intellectualize love, conceptualize love, analyze love, psychologize love, but we cannot create it by any exercise which originates primarily in the intellect. The heart may remain untouched despite all the most careful thought. The one emotion that ideology seems all too readily and too often to generate in abundance is hate. It may, however, also generate a pseudo-love, a counterfeit to stand in the place of what love, by its nature, is meant to be. Ideologically bred “love” is obsession, fanaticism, a sort of veneration of national, class, social, or economic identity. This pseudo-love is usually an amalgam of more than one of the above, and it absorbs the “lover’s” sense of self in the process.
The Christian Story says that the Creator-God did not sit back and shrug. Instead, speaking anthropomorphically, (S)He is deeply grieved, even distressed, and even angry. However, God’s ultimate response is mercy rather than wrath, although wrath has been allowed to fall. If we are willing to face our rebellion and defiance of God, we must see that, just as with human offenders in human society, there is an inevitable day when judgment finds the unrepentant transgressor. This is called “natural consequences”, and it applies in both the physical and metaphysical realm. It also comes as a legal requirement.
Jesus was not saying that people would stop falling in love, stop having sex, or stop caring about family and friends. However, if those other kinds of love are to truly reach their highest potential, they must be ruled by something yet higher – agape. That is what Jesus was predicting would “grow cold” for most people.
