The Quran says:
And the one who has brought the truth and those who embrace it — it is they who are the righteous.
They will have whatever they desire with their Lord. That is the reward of the good-doers.
As such, God will absolve them of ˹even˺ the worst of what they did and reward them according to the best of what they used to do.

The Bible holds out the promise of Paradise on earth.
In it, God will bless mankind with everlasting life. Harmony and peace will prevail. Pain and suffering will be gone. And people will be able to enjoy to the full the natural wonders of planet earth.—Isaiah 65:21-23.

So where does the atonement for our sins fit into this? Good deeds are the flesh, salvation is by Jesus's sacrifice.

I believe the potential reward of good deeds all depends on what side of the Law one is on. If my sins have been forgiven by God because I received His grace through my faith in Jesus Christ, then even the smallest good deed will be rewarded greatly. But if I have not been forgiven of sin because I refused the atonement offered through the sacrifice of Christ, then no amount of good deeds will be able to buy my soul out of Hell.

But what is the reward of faith? Atonement = at one ment. I will be as one with the Son of God dwelling in the perfect presence of my loving Father forever.

There are also some sweet promises of gifts that God will give to the faithful, which are written in Revelations, chapters 2 and 3.

2:7 “To him that overcometh will I give to eat of the tree of life, which is in the midst of the Paradise of God.”

2:10 “Be thou faithful unto death, and I will give thee a crown of life.”

2:17 “To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving [except] he that receiveth it.”

2:26 “And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations...”

2:28 “And I will give him the morning star.”

3:5 “He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before His angels.”

3:12 “Him that overcometh will I make a pillar in the temple of my God; and he shall go no more out: and I will write upon him the name of my God, and the name if the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name.”

3:21 “To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.”

I think that the most important thing is the work of man in this world. If his deeds are righteous, the prophets will intercede for him for his minor sins.
Quran ;
'Those (are happy indeed) whom the angels cause to die while they are pure, saying, `Peace be upon you! Enter Paradise because of that (noble deeds) you have been doing.´

Examples of good deeds and rewards in Quran;
Indeed, the God fearing shall be in the midst of Gardens and [beside] Springs. Receiving what their Lord has granted them. Indeed, they were formerly the good-doers [in this world]. They used to sleep but little by night. And at dawn, they were invoking [God] for forgiveness. And in their property there was the right of mendicants and the deprived.

More examples of good deeds and rewards in Quran;
The believers must (eventually) win through,- Those who humble themselves in their prayers; Who avoid vain talk; Who are active in deeds of charity; Who abstain from sex, Except with those joined to them in the marriage bond, or (the captives) whom their right hands possess,- for (in their case) they are free from blame, Those who faithfully observe their trusts and their covenants; And who (strictly) guard their prayers;- These will be the heirs, Who will inherit Paradise: they will dwell therein (for ever).
