(1Ti 4:2) “Speaking lies in hypocrisy; having their conscience seared with a hot iron;” Continue to read that which follows and you will find them teaching “extra-biblical” things, adding to the Word of God. By the way, those things will be said to “keep” one saved. Remember, salvation is a free gift of God through the blood of His Son. Yes, we are to live holy lives, but it is the Word of God that teaches us “what and how”. They are not “to save” but because we are saved.
