7598 Examining spiritual good.... feeding the word....
May 11, 1960: Book 80
You may only accept as truth that which has its origin in Me. And thus you have to check where spiritual knowledge has originated which is presented to you as truth. And you will be able to do this if you are serious about recognizing truth or error, and if you approach Me for spiritual enlightenment that you will think correctly yourselves and thus also judge correctly. And you will mostly find out that it is spiritual knowledge passed on from person to person, the origin of which you are no longer able to ascertain. And then you will do well to inform yourselves as to what extent such spiritual knowledge corresponds to the word conveyed to you from above by Me.... The truth has to come forth from Me in order to be able to be addressed as truth. And again and again My pure word has also been conveyed to earth from Me.... Therefore it must be able to be compared and correspond with the spiritual knowledge which is offered to you from outside. And then you will recognize for yourselves to what extent truth has been offered to you. But you should never accept it unchecked, and if you can no longer ascertain its origin then be careful with accepting it, for only pure truth will result in spiritual gain for you, whereas error or lies mean danger for your souls. But this examination is usually omitted.... And therefore much error has crept into My gospel, it is no longer the pure teaching as I Myself proclaimed it on earth. Many changes have been made and people no longer know how to distinguish between the pure truth from Me and the humanly added extras and represent everything as 'divine word'. But if 'My word' is to remain in existence for all eternity I have to convey it to earth again and again anew, because imperfect people do not keep anything pure but in their imperfection also disfigure the most perfect, My word.... and thus I must always ensure that My pure word is conveyed to people so that My word will be fulfilled: “Heaven and earth will pass away but 'My word' will remain for all eternity...." And you humans should do your part, you should want the truth to be offered to you by Me, you should pay attention to what spiritual knowledge is then brought to you from outside, you should pay attention to the origin and desire that God Himself may address you.... And I will do so by awakening your spirit and you will brightly and clearly recognize where error has crept in and reject it as such. You are capable of doing so if only you are willing to receive truth and intimately unite with Me and appeal for the supply of it. Then your spirit will be awakened and able to precisely distinguish truth from error, and you will be able to book a spiritual benefit for your souls which only truth can bestow upon them. And you need never fear that you yourselves are incapable of rightly judging what is truth and what is error.... Your will and desire for truth also guarantees you such, because I Myself do not want you to go astray, that the truth is withheld from you by My adversary and his representatives on earth. Thus I will help My own to find the truth, only you should want to belong to My own yourselves, i.e. strive towards the truth and thus towards Me Myself, Who is the eternal truth. It is all so simple and should be understandable to you humans that I only ever want to make the truth accessible to you, thus everything is done on My part to bring you into possession of truth.... And you need only want to live in truth and your will will be complied with. But you should never unquestioningly accept spiritual knowledge which is given to you by people, for only a serious examination can guarantee you the supply of truth, otherwise you will be indifferent and never be able to distinguish error from truth because you lack the serious will to do so. You can and will receive everything you desire from Me, yet without your desire I withhold Myself because I respect your free will, because My grace cannot work against your will either...._>Amen
