First Corinthians 13 emphasizes the primacy of love, even over faith itself. Though I speak with the tongues of men and of angels, and have not love, I am become as sounding brass, or a tinkling cymbal. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not love, it profits me nothing. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.
Hatred stirs up strife, but love covers all offenses.
Above all hold unfailing your love for one another, since love covers a multitude of sins. Jesus Christ IS the picture, the perfect embodiment of Love. By our own flawed human nature, it is almost impossible to love our neighbor as we love ourselves. Maybe some few people can do it, but most people cannot even come close. But when we accept Jesus Christ as our Lord, His Holy Spirit enters us and dwells within us, transforming our flawed nature into a more perfect nature, more like His own.
