4103 Voice of the spirit God's voice.... protection from erroneous thinking....
August 12, 1947: Book 50
You need never doubt that the voice of the spirit teaches you correctly, for it is God's voice.... You need never assume that beings other than God-devoted beings can influence you if you first commend yourselves to God in prayer. The connection you establish with God through prayer protects you against forces which would like to impart other than pure truth to you, and your own line of thought will never lead you astray, because good spiritual forces protect you from receiving the thought material of impure beings. And yet you must always take care that you eliminate bad influence through your will yourselves, so that the battle between the world of light and the forces of darkness cannot break out in the first place, so that only good beings have access to you, which only the human being's will can accomplish. For it alone is decisive as to which forces approach him. If your will is turned towards truth and therefore also towards God Himself, your thinking will always be right, it will correspond to the spiritual good which you receive through the working of the spirit within you; the voice of the spirit will always instruct you in divine wisdom, and everything you think, do and speak will correspond to God's will, Who works in you through His spirit Himself and, through His presence, constantly keeps all imperfect spiritual things away from you and prevents them from distressing you or winning you over. You can be completely certain of His protection, you can also be certain of His love which protects you from all harm to your soul, and you can always regard every advice, every instruction and every other announcement as His word, as His expressed proof of love, which He constantly wants to give to you so that you will recognise and love Him and remain in constant contact with Him. For He gladly dwells where a human heart opens itself to Him, loves Him and deeply desires Him.... And there is no more intimate union with God than through love.... Where love is practised, God will always be present and will reward the earthly child a thousandfold for its love. But the most beautiful reward on earth is His word, which sounds in the human heart.... Anyone who reaches this state can consider himself extremely fortunate, for he has the undeniable proof that God loves him and wants to make him happy and makes this known through the sounding word. But then there is no longer any doubt, then the human being on earth has already reached the degree his soul needs to unite with God. Then he will only live in order to fulfil a mission assigned to him, yet his longing will now constantly be directed towards the spiritual kingdom in order to be and remain intimately united with the aim of his longing, with God, for all eternity....
Amen
