You seem to be using the word "guarantee" as a modern rendering, rather than what the original word means.
It's a down payment, or earnest.
IOW He has done His part, to show us He will make good on His promises, so all that is left is for us to make good on our commitment when we committed our-self to Him in obedience of the Gospel.
The Holy Spirit that we have in this life is the down payment, until the Day of Judgement, in which each of us will be Judged, to determine our deeds.
28 Do not marvel at this; for the hour is coming in which all who are in the graves will hear His voice 29 and come forth—those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation. John 5:28-29
- those who have done good, to the resurrection of life
God who “will render to each one according to his deeds”: 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; Romans 2:6-7

On that Day, the Lord will be looking for those who were faithful with the measure, each one had been given.
20 “So he who had received five talents came and brought five other talents, saying, ‘Lord, you delivered to me five talents; look, I have gained five more talents besides them.’ 21 His lord said to him, ‘Well
done, good and faithful servant; you were faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.’22 He also who had received two talents came and said, ‘Lord, you delivered to me two talents; look, I have gained two more talents besides them.’ 23 His lord said to him, ‘Well
done, good and faithful servant; you have been faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.’
24 “Then he who had received the one talent came and said, ‘Lord, I knew you to be a hard man, reaping where you have not sown, and gathering where you have not scattered seed. 25 And I was afraid, and went and hid your talent in the ground. Look,
there you have
what isyours.’
26 “But his lord answered and said to him, ‘You wicked and lazy servant, you knew that I reap where I have not sown, and gather where I have not scattered seed. 27 So you ought to have deposited my money with the bankers, and at my coming I would have received back my own with interest. 28 Therefore take the talent from him, and give
it to him who has ten talents.
29 ‘For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away. 30 And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.’ Matthew 25:20-30
Those who produce nothing with the measure of His Spirit they had been given have even what they received from Him taken from them.
- even what he has will be taken away. And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.’
Jesus made it clear, about that Day, and those who were fruitful and faithful with the measure they had been given, verses those who produced nothing with His life they had been freely given as a gift.
Then the King will say to those on His right hand, ‘Come, you blessed of My Father, inherit the kingdom prepared for you from the foundation of the world:
for I was hungry and you gave Me food;
I was thirsty and you gave Me drink;
I was a stranger and you took Me in;
I
was naked and you clothed Me;
I was sick and you visited Me;
I was in prison and you came to Me.’
Matthew 25:34-36
God who “will render to each one according to his deeds”: 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; Romans 2:6-7
- eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality;
