So, number one, false doctrines will not be found in the Word of God, but are the additions or omissions by man following a voice other than God's.
Also, interpretations. As God's word states:
Knowing this first, that no prophecy of the scripture is of any private interpretation.
I have found this to be one of the greater challenges in understanding God's word. Simply let it say what it means and mean what it says without my mind corrupting the meaning.
Anyway, good post and God bless!
