The answer from God’s word:
“
The Bible has been accompanying man for several thousand years of history, and people all treat it as
God, and in the last days people even replace God’s place with
the Bible, which is a thing greatly loathed by God. So, in His leisure time, God has to make clear both the inside truth and the origin of the Bible. If not, in man’s heart the Bible can still take the place of God, and people will still condemn and measure God’s doings with the letters of the Bible. By explaining the substance and structure of the Bible and the flaws in it, God is not denying the existence of the Bible or condemning the Bible, but giving a proper and appropriate statement about it and showing what the Bible really is, correcting people’s erroneous knowledge about the Bible, so that they all can have an accurate view about the Bible, no longer worship the Bible, and no longer lose the direction—considering blindly believing in the Bible as believing in God and worshiping God, and even daring not to face the true background of the Bible and the flaws in it. After people all have a pure knowledge of the Bible, they will cast it off without any misgiving and accept God’s new word boldly. … Here, the truth God wants to tell man is that no theory or fact can replace God’s practical work and word, and no thing can take the place of God. If one cannot break away from the trapping of the Bible, then he can never possibly come before God. If one wants to come before God, he needs to first sweep away all the things in his heart that can replace God. Thus God will be satisfied. Although here God only gives explanations about the Bible, you should not forget that apart from the Bible, there are many other erroneous things that man truly worships, and that the only things that man does not worship are those truly from God. God just takes the Bible as an example to remind everyone: Do not take the wrong way, and do not go to extremes and fall into confusion again while you believe in God and receive
God’s word.”
