Compassion is an aspect of Divine love that melts all defenses and resistance when anyone's suffering is really seen. There is nothing the personality can do to create compassion, but when we are willing to be completely open and truthful about whatever we are truly feeling, it arises naturally and soothes our hurt. (We could say that truth without compassion is not really truth, and that compassion without truth is not really compassion.) The Divine love that seeks to express itself in the world through us is a powerful force that can break through all of the old barriers and untruths that have accumulated in us.
You will only arrive at what you are aiming to achieve through the cultivation of two fundamental attitudes of soul. You must nurture a true love for what you represent, and also an insightful love of humanity. Be quite clear that if these two conditions are not met, you may be able to present material ever so logically, you may be able to demonstrate exceptional cleverness, and you will still not achieve anything.
