5310 What comes from above must radiate light....
February 4, 1952: Book 59
You must constantly make it your business to increase your state of maturity, you must constantly strive for perfection, you must constantly strengthen the bond with Me more, you must strive for a complete union with Me, then the separation between us will be more and more abolished, then My flow of strength of love can constantly flow into you, then you will be filled with My spirit.... i.e., that is, nothing will be impossible for you anymore, and then you will also be able to accomplish feats which seem to be supernatural because they can only be achieved with divine strength but which you can now use without measure because it will flow over you without restriction if you want to use it. But now I also want your fellow human beings to take note of what a person in closest contact with Me is capable of, so that they, too, will strive for this state of maturity and thus enter into the relationship with Me, which is their aim on this earth. Therefore, every spirit-filled person will in some way bear witness to Me and for Me.... he will heal the sick who believe in Me, he will hear My voice and thus be able to preach filled by My spirit; he will prophesy, i.e. be able to look into the future, but just as he will be able to see through his fellow human being's thoughts; he will know about things which his fellow human being does not know but only ever give knowledge of them where people's salvation is endangered, just as every spirit-filled person will only ever use his spiritual gift for spiritual life, for Me and My kingdom.... He will try to spread light and therefore be placed into the state of light by My spirit beforehand, which will then enable him to radiate light to his fellow human beings. Yet a spirit-awakened person will never deepen a state of darkness by spreading divine gifts before his fellow human beings which are not recognizable to them as such.... A light must spread brightness, otherwise it is no light.... The prerequisite is that the fellow human being wants to see and recognize.... But where this prerequisite is given and it nevertheless remains dark, there cannot be light, there cannot be spoken of the working of the spirit, which is the emanating strength of My love. People's degrees of maturity are certainly different and therefore also allow for different expressions of My spirit, yet it must always be possible to recognize My divine working if it is to help people achieve spiritual perfection as a life-awakening grant of grace.
Anyone who is therefore of an awakened spirit will be alienated by what is erroneously presented as spiritual activity and eagerly advocated if he cannot recognize any light from above in it himself, if he looks in vain for an effect which promotes the human being's maturity of soul and is, as it were, confronted by an inexplicable process which gives him no inner satisfaction. And such a process would be, for example, a proclamation in an incomprehensible language, the utterance of a being from the spiritual kingdom which seeks to make itself known on earth through a human being.... This being can certainly make use of a human being in order to express itself, yet these are never beings which are intended to bring light to people on My behalf, it is not an outpouring of the spirit upon such people but rather a reaction of a weak earthly spirit to the oppression of a spiritual being which, in rapturous devotion, renounces its own will and therefore is a welcome form for those spiritual beings through which they can express themselves, and in the way they are able to do so themselves....
Everything that comes from above, which is imparted to people on earth in My will, must radiate light, people seeking light must also receive rays of light.... Where the shining of light is missing there is no working from the kingdom of light, and people should not put themselves into a state through fanatical worship where questionable forces can make use of them. The desire for recognition often plays a major role, and every error, every weakness, is exploited by these forces, yet always in such a way that a spiritually awakened person can recognize where the messages come from.... Zeal is certainly to be praised but it is not always appropriate, it does not always produce such results as correspond to My will, which is in a sense anticipated. I let My light shine where it is desired, but the adversary also knows how to light deceptive lights which, however, do not emit any light; and you will always recognize from this that only the eternal light spreads a radiant glow and that the prince of darkness can never illuminate the darkness.
Amen
