I happen to agree with the one who declared no Christian could lose their salvation - it is pretty clear in Scripture that it is a function of grace. If you are "well aware" of the Scriptures, then why do you seem to be denying them? What Hebrews chapter 6 says can be explained BY other Scripture and we should not make a rookie mistake of interpreting a single, not-so-clear verse without using OTHER passages to help explain it correctly.
BTW...I think you owe Eagleone an apology for how you responded. He was nothing but respectful towards you.
I do not apologize for God’s Word and it’s truth, and I am no rookie in God’s kingdom...I feel sorry for you because the Scriptures are right and you are wrong. period. That is my last comment on the subject.
