That is a false teaching.Yes. I realize that this statement will likely be looked negatively upon, because the prevalent teaching is that Christians continue to sin.
Jesus said the truth would make us free, in John 8:32.
The Jews said, "from what ?"
Jesus answered..."Whosoever committeth sin is the servant of sin." (John 8:34)
The truth can free us from serving sin !
As John said, in 1 John 5:17, "All unrighteousness is sin..."However, people may differ in understanding of what "sin" is.
