No willful known sin is forgiven without repentance and there is not a more Scriptural, basic doctrine than that. OSAS blinds people to the most important doctrines of the Bible. Once someone gets so committed to OSAS they will twist ALL contradicting Scriptures to fit their presupposition. You cannot change someones mind on that issue, while they are so committed. There is no prophet in debating or arguing with those committed to this false doctrine – except for the glory of God. Gal. 5:4 “you have fallen away from grace.”
