“If I were called upon to put my finger on the most pressing need of our age, I would unhesitatingly say one thing — maturity.” From that statement, Jones convincingly says that the key to maturity is love. He then traces the nature and meaning of love. Jones writes that when John wrote, “God is love;” all heaven broke out in applause as if to say, “They’ve finally got it.” Jones (and John) are talking about Christian love, which is not just sentiment but real and essential to the development of our own nature. Mature people have learned how to love.
