Challenges and afflictions for some come in copable (if there is such a word) quantities, like parasitic cowbirds. For others they may come in pestilential flocks, like grackles or starlings, but whatever the quantity it is tempting to limit one's Scientific efforts to the demands of personal tribulations, especially when they seem to come in exasperating mongol hordes. Obviously, our first responsibility should be to our own well-being, but taking care that this devotion to self does not become self-indulgent from soup to nuts.
If our hearts withdraw to the selfish confines of a personal material existence, we shouldn't be surprised if the unhealed and unmet needs of a sick and sinful world intrude upon us unbidden. Failing to pray for the mitigation humanity's overwhelming needs we default to some extent on our duty to pray more comprehensively for our own. We are never separate from our oneness with the whole of God's perfect creation, but to ignore the countless evils besetting humanity is to fail to wrestle with and overcome some of the false beliefs which tempt us all and which originate in the basic lie of mortal mind and to invite unwittingly the unclean spirit to take "seven other spirits more wicked than himself, and enter in and dwell there [in our consciousness]: and the last state of that man is worse than the first." (Matt 12: 45)
To human sense the dismaying quantity, depth, and ferocity of the evil, depravity, and cruelty in the world is ineluctable, but we cannot afford to ignore our duty to defend ourselves from aggressive mental suggestion and to refuse to "stand aghast at nothingness". As we heal in our thinking--the only place it ever "exists"--the world's aggressively mesmeric claims, we cannot fail, to some extent, to heal ourselves. Turning our back on suffering humanity or foolishly hoping the bad out there isn't as bad as we don't want to know gives to Satan the only "life" and influence he can ever have.
Note: By "conniptions" in the previous entry I was only choosing an eye-catching word to capture the false nature of material sense testimony. Nothing profound was intended.
