What Does the World Look Like After You Act On It: What would happen if everybody everywhere did what you are about to do?

My dad taught me this. I have never forgotten it. (The Saved and the Reprobate are alike encompassed in the stated imperative.) 

The universe is a BIG thing to consider. Every deed generates a wave spreading everywhere. So ask yourself before your next act of will: "Am I a builder or destroyer of worlds by what I am doing?"

There is a reason behind every act. We must think about that for our actions to be reasonable. If we are driven by impulse rather than thought, the reason for our actions is actually unreasonable; and the immorality of that irresponsibility has universal consequences for which we cannot escape (or deny) responsibility. If you cannot see good expanding to universality from an intended act of your commission, you are acting immorally, and evil is your true motive.

"Kantian Ethics refers to a[n]...ethical theory ascribed to the German philosopher Immanuel Kant. The theory...is based on the view that the only intrinsically good thing is a good will; an action can only be good if its maxim – the principle behind it – is duty to the moral law***. 

Central to Kant's construction of the moral law is the categorical imperative, which acts on all people, regardless of their interests or desires. Kant's principle of universality requires that, for an action to be permissible, it must be possible to apply it to all people without a contradiction occurring. If contradictions occur the act violates Aristotle's concept which states that just actions cannot lead to contradictions. Kant's formulation of humanity...states that as an end in itself humans are required never to treat others merely as a means to an end... The formulation of autonomy concludes that rational agents are bound to the moral law by their own will, while Kant's concept of the Kingdom of Ends requires that people act as if the principles of their actions establish a law for a hypothetical kingdom." 

Obviously, the philosophy is not explicitly Christian, and IS deficient wherever it departs from God's revealed word and its primacy. Nonetheless, as a subset of "truth" insofar as it does not depart from the revealed word and its Incarnation in the Lord Jesus Christ Who IS TRUTH, it deserves reverence. "Revere the truth wherever it is found."

***the moral law: consider equivalence to NATURAL LAW.  From that consideration revere the revelation of Natural Law and its undeniable significance found in Paul's Epistle to the Romans Chapters 1:16-32; 2:1-29; 3:1-28 

Seek ye the Lord while He may be found. May we be covered by the blood of the Lord Jesus Christ; and all our transgressions forgiven. By His grace may we be delivered from the wrath of God which our deeds apart from Him deserve.
