God is love and we know the children of God by their love. Any truth which is made to stand in opposition to love is a dead carcass which by its corruption becomes evil. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. But the greatest of these is love. We can possess the greatest of gifts, and make the greatest of sacrifices, but if we lack love, we are nothing and we gain nothing.
Love is the great gift.
All else, no matter how valuable is worthless without love. All else, no matter how great, is nothing without love. Human nature is to corrupt what is good. American Christians are much like the nation of Israel in Isaiah's day. The American church is splintered into denominations which boast about some truth, gift, or virtue that they possess.
