In our modern age in the West, ideology now largely replaces religion. The God-shaped void in the human soul must and will be filled with something. With Christianity now largely treated as irrelevant, ideology readily steps into the vacuum. Often, the ideology just slithers into the emptiness via materialist rewards, peer pressure, educational indoctrination, and popular culture. With the modern doctrine of the separation of Church and State cemented in place, even many professing Christians leave their religion inside the Church door, then lock in a set of ideological constructs, sometimes sprinkled with Holy Water or, in the Fundamentalist formulation, with the “Blood of Jesus”, to salve their consciences.
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.
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.
