By pretending that we don’t know what parts of the Bible God “really” inspired, they imply the additional portions in italics:
Matthew 4:4 But he answered, “It is written, “ ‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’ But we don’t know which words came from the mouth of God, so what I just said was pointless. Never mind.”
2 Timothy 3:16–17 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work. But we don’t know what “all scripture” really is, so we don’t know what is profitable for teaching, etc., and the man of God can’t be complete and equipped. Oh, and that just triggered me by not mentioning women, and triggered me even more by pretending there are two genders!
Hebrews 4:12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. Except that we don’t know what the word of God really is, so never mind.
You could literally do this for many hundreds of passages. These people only thrive because of biblical illiteracy, a severe lack of common sense and a insatiable love of the world. While they are busy abusing the scriptures, may God open their eyes to truth that it all turned out just as He wanted it to!
