We are at the beginning and end of so much that descends and ascends upon us. As new technologies transform standards, old human laborious capacities of current worth will have to grapple with many of these fundamental changes, redefining security and basic human efforts. Left in realms of miraculous achievements, social conditions will be challenged climbing toward or running from all the nebulous overwhelming voids, new to human creation and invention, avalanched upon our children’s children, truth will remain in the midst of lies. Skewing exponentially the times unwind and without moral decency to knit civilization in a bond of unity, no compass will direct us. In a troubling world God has always led the humble to sanctuaries beyond human comprehension, while darkness consumes itself in evil pursuits, God’s own blessings come to the humble remnant. To count the stars of heart is a task left to the dreams of tomorrow.

If the chains of evil cannot be broken, a possible time is coming where the wasted petty arguing we do today in the modern civilized world will become so insignificant, as nations implode upon the shear hate for life, and then comes the assault on all those that would hope for peace as the children cry. Most of time is filled with the cries of all that is unjust. Truth stands for justice and our senses are deceived as lies have too often overwhelmed times, past regrets, where ashes crush the people.

If through our tears we can regain laughter, in this hope might strength return with purpose where commendations replace criticisms, and godly humbled hearts can unapologetically rest upon love shared for one another in the open. Hate is the cancer that steals laughter, that one precious component of innocence. Truth is not right when it rests in lies. Those today screaming victimization due to prejudice often are the ones found to be the most prejudice, unable to bury the hate that divides all cold hearted souls to turmoils within self-inflicted isolated narcissistic oblivions. Timeless corruption, for all that is unholy, and whom passionately hate life itself with anger as their only vision, this is why security implementations must take precedence into the foreseeable future, and even more so as governments collide, and perhaps internally splinter. May our children find greater unity than the divisions we now must face with piercings of heart.
