Rightly divided, the Word reveals that one believes in their heart, which is not possible in the stony heart of a person who is hostile in their mind to God ... plainly spoken, the Truth cannot take fruitful root in such a heart... even Paul acknowledged that he needed to be rescued because he was sold into sin and a slave to it ... and that it was Jesus Christ who rescued him, not his so-called free will. He freely acknowledged that his will was not free, and you would do well to do the same.The Greek in Ephesians 2:8 makes it very clear.
The entire 'doctrines of grace" fails on this one statement correctly understood in the original language and linguistics, although God knows the propaganda against this has been churned out over and over again.
