4515 Condition for right representatives of God: working of the spirit and truthful knowledge....
December 17, 1948: Book 52
Anyone who wants to call himself My representative on earth must also instruct his fellow human beings in accordance with the fullest truth. Thus he must possess it himself and therefore be introduced to the pure truth by My spirit through My word. He cannot teach if he has not grasped the meaning himself, if it is not fully comprehensible to him how My word is to be understood, which can only be understood in a deeply spiritual way. Hence he must be so inwardly devoted to Me that I Myself can work in him through My spirit, only then will he be a true representative of My name, then he can be active for Me and My kingdom and work for the blessing of his fellow human beings on earth. But it is not enough for a person to say to Me: "Lord, lord...." if he confesses Me with his mouth and wants to express his bond with Me through words.... I only look at the heart, but My eyes penetrate it and not the smallest corner remains hidden from Me. I know every thought of the human being and therefore also know the innermost life of the soul of every person who calls himself My representative on earth.... And in accordance with My eternal order I cannot deviate from the conditions I have attached to the working of My spirit in the human being. I cannot enlighten a person's thinking who has not shaped himself to receive My spirit; he will always walk in ignorance, My word will be and remain incomprehensible to him, and consequently he will not be suitable as a teacher for his fellow human beings as long as he has not established the heartfelt bond with Me through loving activity, which then also results in the working of the spirit. And since I am therefore well able to see through people's hearts, I Myself choose the suitable hearts which are suitable as receptacles for My spirit and pour the truth into them.... I Myself train them as teachers because it is urgently necessary that people are enlightened, that My word is conveyed to them in its purest form, that they find the truth if they look for it. And I will also always support these My right representatives on earth with My strength so that they can teach without hesitation and are always active in My will. The truth shall be spread and I bless everyone who contributes to it, who shapes himself such that I Myself can work through him.... that he is truly My representative, who can proclaim My word and make My will known to people and thereby bring light to all people who walk in darkness and desire light....
Amen
