1114 The inner voice.... voice of the conscience.... audible voice....
September 25, 1939: Book 20
The inner voice informs the human being of God's will, and therefore it should be heeded first, for if he obeys it he is also walking the right path. In order to hear the voice within himself, the human being must be prepared to comply with God's will, he must, as it were, ask for divine instructions in order to be able to fulfil them, and if he expresses this will, God will also make Himself known to him, in different ways depending on his worthiness. Mostly through the voice of conscience.... This is audible to every person who listens inwardly, it is the admonition to do good and the warning to refrain from evil, it is the surest signpost, the exhortation and the warning signal from on high. He who pays attention to his thoughts will regocnize that they flow in upon him both desired and undesired. So often thoughts arise which are annoying to him, which want to determine him to do something or prevent him from carrying out something, and such thoughts are always the inner voice audible to man, the voice of conscience. If a person allows himself to be guided by such thoughts, always with God in mind and with the will to do what is right, he will truly be guided correctly. But if this voice is not heeded, the call from on high will become weaker and weaker until it finally falls silent completely, for the will to do good, the prerequisite for hearing the inner voice, is not present. However, if the human being establishes an intimate relationship with the father in heaven by eagerly following the divine will, the voice will resound all the louder, for where the will of the earthly child completely subordinates itself to the divine will, there the lord will let His voice resound audibly and remove all barriers which had been erected between Him and the earthly child. Truly, no special external gift is required for this, but a truly God-loving heart and most intimate devotion suffice, for in such a heart the lord and saviour Himself can take up residence and now speak clearly and audibly with His child. And this triggers all the delights of heaven in the earthly child who is so happy. It may only desire the divine voice and will now never make a wrong request, and the divine saviour Himself instructs it in the most loving way and announces His will to it. And every human being is entitled to this extraordinary grace and yet it is disregarded.... To be in direct contact with God, to be allowed to hear His kind fatherly words and to draw grace, comfort and strength from them in unimagined abundance is truly God's greatest gift of grace.... and yet it is so little appreciated, and in times of adversity mankind suffers through its own fault....
Amen
