“One day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight.”
Whether we reference these words from Isaiah or Dr. King, it appears they are truly prophetic words: Entropy - The degradation of the matter and energy in the universe to an ultimate state of inert uniformity - https://www.merriam-webster.com/dictionary/entropy. In the same way that the turbulent forces which create ripples in the pond above will eventually cease to administer their influence, all other forces which aim to create inequality will placidly smooth like an untouched pond.
It doesn’t take long to find that research on heart health and longevity indicates anger/bitterness in shortening lifespan and forgiveness in lengthening it. That is, how you live in your spirit probably impacts health more than diet and exercise combined: https://www.hopkinsmedicine.org/health/wellness-and-prevention/forgiveness-your-health-depends-on-it. And, although grudges toward individuals will torment and kill you, what we often don’t think about is broad grudges and grand hatred. To be clear, bigotry, racism, sexism, ethnocentrism, etc., are broad grudges against a whole group. They’re intense and massive grudges toward ideologies, political world views, or even greater abstract ideas of others.
I’d also caution against thinking you’re immune to this just because of the “rightness” or “righteousness” of your side. The mere effort to exalt “our guys” with the diminution of “their guys” IS a constant grudge, an ongoing anger and rejection of a whole group. That anger is inside you, not burning a hole in your opposition. It’s burning a hole inside of you.
But that feeble attempt to raise up your side and subjugate the other side will end. It is a physical law that an absolute equality come about. We know it. We sense it. And we can palpably feel the consequences to our internal state when we defy it. No matter what wrongs we do in life, no matter the greatest attempts at bigotry and inequity, the universe will all come to a state of total uniformity.
Our futile efforts at bolstering “our side” will one day be totally wiped out. And I can’t help but believe that rebellion against equality will come at overt and immediate costs to our health in that very moment: https://washingtonmonthly.com/magazine/janfeb-2013/is-inequality-shortening-your-life-span/. Hatred in our souls conflicts with the very nature of Nature; and that conflict robs us of peace. It is inevitable, whether we believe in divine providence or disbelieve in divine providence. It is the natural procession of ultimate time. Inequality is at odds with the laws of physics.
