In contrast to the philosophies of atheism and pantheism, Jesus Christ put love at the center of life. Love is the central concern in Christ‘s apologetic to the world. Both John 13:35 and John 17:20- 23 indicate that the world will not know who Jesus is through the means of his ultimate apologetic-love among believers-unless believers demonstrate his love first to each other and then to the watching world. The New Testament emphasis on agape is utterly unique among world religions. The statement “God is love” (1 John 4:8, 16) cannot be said in any other view of life. The ultimate demonstration of love is the cross, and that is the painful, self-sacrificial, other-directed love to which we are called.
