I respect your thoughtful questions. Thank you.
John 5:24 above tells us about "salvation" from death. Agree?
Romans 5:9 above confirms "salvation" by his blood and tells us that there is a wrath to come that we will be spared from. Paul does not go into the circumstances that may happen that will bring about judgment to these same "saved" persons.
However, he does so in Hebrews 10 "For if "
we" go on sinning willfully
after receiving.."
26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a terrifying expectation of judgment and the fury of a fire which will consume the adversaries. 28 Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses. 29 How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay.” And again, “The Lord will judge His people.” 31 It is a terrifying thing to fall into the hands of the living God.
32 But remember the former days, when, after being enlightened, you endured a great conflict of sufferings, 33 partly by being made a public spectacle through reproaches and tribulations, and partly by becoming sharers with those who were so treated. 34 For you showed sympathy to the prisoners and accepted joyfully the seizure of your property, knowing that you have for yourselves a better possession and a lasting one. 35 Therefore, do not throw away your confidence, which has a great reward. 36 For you have need of endurance, so that when you have done the will of God, you may receive what was promised.
37 For yet in a very little while,
He who is coming will come, and will not delay.
38 But My righteous one shall live by faith;
And if he shrinks back, My soul has no pleasure in him.
39 But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.
Sorry to make this too long, but there is so much scripture that I could give you...
QUESTION: In the following illustration, when the "servant" was forgiven his debt, was he "saved" from the consequences of not being able to pay?
Answer: Yes.
QUESTION: Later, after being "saved" from the consequences of paying back a debt he could not pay, did "his lord" level consequences back on "his servant" for failing to meet the reasonable expectations of having been forgiven? Did this negate the original "salvation" granted, or did the "servant" forfeit it by failing to meet "his lord's" expectations?
23 Therefore is the kingdom of heaven likened unto a certain king, which would take account of his servants.
24 And when he had begun to reckon, one was brought unto him, which owed him ten thousand talents.
25 But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made.
26 The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all.
27 Then the lord of that servant was moved with compassion, and loosed him, and forgave him the debt.
Recognize that Jesus has defined the relationship of “Lord” and “Servant”. If Jesus says that this person is a “servant” over whom He acknowledges “lordship”, then we had better be careful not to dismiss it as an unbeliever.
Jesus continues…
28 But the same servant went out, and found one of his fellow servants, which owed him an hundred pence: and he laid hands on him, and took him by the throat, saying, Pay me that thou owest.
29 And his fellow servant fell down at his feet, and besought him, saying, Have patience with me, and I will pay thee all.
30 And he would not: but went and cast him into prison, till he should pay the debt.
31 So when his fellow servants saw what was done, they were very sorry, and came and told unto their lord all that was done.
32 Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me:
33 Shouldest not thou also have had compassion on thy fellow servant, even as I had pity on thee?
34 And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him.
35 So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.
It is unmistakable that Jesus is warning believers/disciples/fellow servants those who are in covenant relationship with Him, that there are expectations that have benefits and consequences.
He does not deny that the “wicked” servant is “his servant”. He is telling His servants that He has expectations that must be met or there are consequences.
