When I say ‘scripture”, I am of course, in the context of our discussion here, referring to the gospel of grace in the New Covenant found in the NT which replaced the Old Covenant of the law of the OT (Heb 8:13).
All of the NT scriptures you cited refer to those outside of faith in Christ where, yes, there does comes a point when a person has said no to Christ for the very last time, and sadly are lost forever.
But that is not the theme of this thread which is salvation initially and continually by grace alone and not works.
Pay attention.
It seems you at least acknowledge in the NT where God does withholds His grace and a person is lost forever. That's a start.
That IS the theme of this tread when I stated that sodomy is an abomination before God and is an indication that a person might have cross that line based upon Romans 1. That is not to say that a person still cannot be saved from that situation. It only is to say it is an indication of deep depravity in their lives.
People simply don't wish to acknowledge the depravity of man and how rebellious we are. Instead they simply want to focus on God's grace and goodness. There are two sides to this coin.
