As a general rule, decide whether a thing is permissible by the effect it produces within. Permit yourself what is constructive, but never what is destructive.
It is up to us now to either bury our conscience under the ground, or to have it shine forth and illuminate us if we obey it. When our conscience says to us, 'Do this,' and we treat it with contempt, or it says it again and we refuse, then we are trampling it down, burying it under ground. Thus, it cannot speak to us clearly because of the weight upon it.
Conscience in men is nothing else but the voice of the omnipresent God moving in the hearts of men, as He Who alone Is and has created everything, the Lord knows all as Himself - all the thoughts, desires, intentions, words, and works of men, present, past, and future. However far in front I may let my thoughts, my imagination, run He is there before me and I ever inevitably finish my course in Him, ever having Him as the witness of my ways. 'His eyes are open upon all the ways of the sons of men' (Jer 32:19). 'Whither shall I go from Thy Spirit, or whither shall I flee from Thy presence?' (Ps 139:7).
When God, using our conscience, calls us to righteousness and yet our self-will opposes Him, He respects our freedom and lets our own will be done; but then, alas, our minds grow dull, our will slack, and we commit iniquities without number. On the other hand, the fruits of the spirit are soon granted to them who follow the commandments of Christ our Lord.
Do not disregard your conscience, which always counsels you of the best. It puts before you divine and angelic advice; it frees you from the hidden stains of your heart, and will make you the gift of free speech with God at the time of your departure.
Keep your conscience keen and bright, and refrain from hankering after, or expecting, consolation. Leave that to God. He knows when, where, and how to give it to you.
The moral character and moral value of man's personality depends most of all on the direction and strength of the will. Of course, everyone understands that for a Christian it is necessary to have first, a strong and decisive will, and second, a will which is firmly directed toward the good of his neighbor, toward the side of good and not evil. How is one to develop a strong will? The answer is simple: above all through the exercise of the will. To do this, as with bodily exercise, it is necessary to begin slowly, little by little. However, having begun to exercise one's will in anything ( e.g., in a constant struggle with one's sinful habits or whims) this work on oneself must never cease. Moreover, a Christian who wishes to strengthen his will, his character, must from the very beginning avoid all dissipation, disorder and inconsistency of behavior. Otherwise, he will be a person without character, unreliable, a reed shaking in the wind, as we read in Holy Scripture.
No one can be saved without the renunciation of his will, even though he might struggle fervently, for our will and our manner are like a bronze wall between us and God.
When we live according to the moral principles of our faith, those around us may respond in three possible ways. First, they may be so impressed by the example of our goodness, and so envious of the joy which it brings, that they want to join us and become like us. That is the response which we most earnestly desire. Second, they may be indifferent to us, because they are so bound up with their own selfish cares and concerns; although their eyes may perceive our way of life, their hearts are blind, so we are unable to stir them. Third, they may react against us, feeling threatened by our example and even angry with us; thus they will cling even more firmly to their material possessions and selfish ambitions, and slander us at every opportunity. Naturally, we dread this third type of reaction, because we want to live in peace with our neighbors, regardless of their personal beliefs and values. But if no one reacts to us in this way, we must wonder whether we are truly fulfilling the commandments of Christ.
There is nothing more burdensome and grievous then when conscience accuses us in anything, and there is nothing dearer then calmness and approval of the conscience.
