The cross would mean that the willingness to endure discomfort, suffering and humiliation is such a powerful way to convey love that the cross is the center of the love that rules the world. Jesus offered nothing but love when those around him gave him nothing but hate. We see no sign of resentment, bitterness or anger in the words of Jesus on the cross. The cross shows us that the only victory in life is to love, with loyalty to God through all of life's ups and downs, for richer or poorer, in sickness and in health. Jesus showed us His commitment to us through death on the cross. He demonstrated his loyalty.
Our society today is sorely lacking the guiding principles of loyalty and commitment. Half of all marriages fail. Even in today's job market, many people are still changing jobs almost as often as they change their socks. People change their "spiritual path" as it suits their whims, choosing whatever agrees with them as the truth at that particular time. Truth in our culture is relative and arbitrary.
Once upon a time, there was a man who made the deepest and most enduring commitment possible to you, even if you never loved Him back.
Many people don't like to look at the crucifix, saying such things as, "He's off the cross now. Let's talk about the resurrection." Jesus is never off the cross. He is married to it. The cross is His perfect commitment to you. Jesus rose and Jesus lives but the sacrifice He made on the cross saturates every moment we live, each time our heart beats or we blink an eye.
Jesus is a King who reigns from the cross. He needs no other throne to prove that he is God or to show he is important. The cross says it all.
