The further assertion, “...enduring to the end is how we qualify for Grace” is yet another phrasing of the works based religion of catholiciism. The Bible passage we expect to now be taken out of context to defend this demonic lie will reveal the subtlety of the lie. A catholic is taught to believe they must QUALIFY for Grace! How demonic and blatant can it get, yet catholics are blind to the Truth of that lie. It is by Grace we are saved, not of works lest any catholic boast of his qualifying worthiness!
Certainly I have never said that works save anyone. Works are simply the evidence of faith. Grace will not save the faithless. Again you show me your works and I will show you your faith said the Apostle James.
