Does God make idle claims?
Conditions must be met if benefits are to be received. Throughout the New Testament, the word 'if' is used many times in association with salvation. When the conditions God sets by these 'ifs' are not met then an individual can't expect to receive the rewards.
John 15:6----If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned.
So, any one who does not abide in Christ, is severed from the Vine.
Abide: to endure without yielding, to remain stable or fixed in a state.
1 Corinthians 15-2: "By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain."
Paul apparently believed that a person is only saved if they continue to believe in the gospel. If they lose faith in the gospel, presumably they lose their salvation.
Of course, Bill being a conservative theologian will say many verses refer to those who were not really initially saved, but I don't see the word "initially".
The first two verses of Hebrews 6:4-6 define precisely an individual who had been saved & was receiving the benefits of salvation. The last verse states clearly that a person is quite capable of falling away from the faith...and if they do so, that it is impossible for their salvation to be renewed.
2 Peter 2:20-21 implies that people will be more viciously treated after death by God's wrath than those people who were never saved.
Ephesians 5:5-6 appears to be one of several blanket condemnations in the Bible of people who will be denied access to heaven because of their conduct. There's no exception made for saved persons. "No person" would seem to mean what it says, "no...person". God's wrath would imply permanent residence in Hell.
Since 100% of the human race does wrong or some evil sometime during their life, many scriptures imply that we are all doomed.
I could go on & on but I have to stop somewhere.
