Okay, now that I have your attention....
Everything is worthless and your point fails if God makes salvation conditional. Now you understand language like I do.
Gods phrases are open and straightforward. Sin is wrong, leads to death and judgement. Sinners are doomed without forgiveness. We only gain forgiveness through faith demonstrated by works.
"For God so loved the world that He gave is only Son that whoever believes in Him may not perish but have eternal life"
The condition is belief. Now listen to the parables. Belief to the end, life transforming, faithful belief.
All the promises are to those who stand in this place. It is that simple.
This whole construct is built upon sin being destruction of relationships and love. You want to say all christians continue in sin, and disbelief, so one flash in the pan is enough to fulfill all the promises given by God or He is a liar. So also speaks the enemy.
You would have a husband is bound to his wife even though they commit adultery, the promises still stand.
Or equally if the husband commits adultery, the wife must honour the husband.
Everyone says one simple point:-
Nothing impure will ever enter it (the new Jerusalem), nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb’s book of life.
rev 21:27
Then he told me, “Do not seal up the words of the prophecy of this scroll, because the time is near. Let the one who does wrong continue to do wrong; let the vile person continue to be vile; let the one who does right continue to do right; and let the holy person continue to be holy.”
Rev 22:10-11
The people who hold your position deny that anyone can be "holy" yet here is John saying, "let the holy person continue to be holy."
Of those written in the book, they are eternal, but they could walk away, or else choice and love do not exist.
The fact that God promises to His people to be faithful and not turn one away, does not mean he is faithful to the rebellious, those who tasted but cursed the King. Surely those who walk in such a way deserve more dishonour than those who have not even tasted.
What did Jesus say of the cities that refused to accept the good news when preached to them,
Truly I tell you, it will be more bearable for Sodom and Gomorrah on the day of judgment than for that town.
Matt 10:15
Now dear reader these believers are very kind hearted, those who tasted of grace and love, yet went back to sin and death should be saved, because though they sinned against God in ignorance, now sinning against God in knowledge should be forgiven. I suggest it is their own sins and bad conscience they wish to be forgiven, and they doubt their own salvation without this forgiveness, so it is their own unbelief and lack of understanding of the King which they are expressing.
In our eyes the Lord is brutal, but then who is God and who is the sinner. For us sin has always been minor, a small error, something of convoluted minds, which really does not effect the relationship. Ever listened to an adulterer. It meant nothing, I still love you, really.... So will plead all sinners on judgement day who have not entered the Kingdom and stayed true to their King.
