You will never convience me that man is the cause of his eternal justification, there are just too many scriptures that affirm that it is Christ that justifies man and not man justifing himself.Rom 5:9, being now justified by his blood. Rom 8:30, whom he called, them he also justified. Tit 3:7, that being justified by his grace.
I don't believe there are any here who would disagree with what you have written here.
