4591 Love condition to be able to believe God’s word....
March 20, 1949: Book 53
The stronger your love for Me, which is expressed in active neighbourly love, the more receptive you will be for My word, wherever and in whatever form it is offered to you. Then you will recognize the father's voice in My word which, however, will remain alien to you and leave you untouched if you lack love. And this is the solution to the riddle why so many people pass by and remain unimpressed by the word which is offered to them from above. They don't have love and therefore don't press towards the father like children, which is why they are also unable to hear the father's voice. And therefore you should first preach love if you want to be successful with the greatest evidence of My fatherly love.... with My word, which is to change people. You should only acquaint them with the commandment, the observance of which signifies a way of life according to My will. Only then will the human being be able to be guided into truth through My word, i.e. the knowledge which is now imparted to him will now be understandable and believable to him. For faith is only the result of love, without love it is not possible for the human being to believe what spiritual knowledge is conveyed to him. And thus a high degree of love must fill the human being if he wants to hear My voice resounding within himself. You all could provide yourselves with the evidence if you believed these words and seriously made an effort to increase your degree of love. But your will is not enough for this, and you also make too little use of the grace of prayer to strengthen your will, to gain strength for loving activity, and thus you will never be able to penetrate the deepest knowledge which is soundly offered to you by Me Myself if you possess the necessary maturity. Hence you will only ever have to believe but you will not be able to provide yourselves with the evidence of the truth of what is imparted to you through My word. You must believe but you can also do so if only you live in love. Then your faith will be a convinced one, even without proof, for love is always the strength which enlivens everything and also turns faith into a living faith....
Amen
