I see five archetypes of people:
A) Have faith AND do good deeds
B) Sin a lot so that the deeds are not good, but have faith and ask for forgiveness
C) Have faith but are misguided in it, hence commit severe sin without recognising it, hence not asking for forgiveness
D) Have no faith in God (maybe atheist or following some esoteric teaching), but have a good heart and try hard to do the best in the sense of the non-religious commandments
E) Have no faith AND sin a lot.
I see the Quran and the Gospel in line promising A and B will enter Jannah (Final Paradise). At least the Quran is also explicit saying E won't be able to enter Jannah.
We have no clear promises for C and D. I wish the best for D, but God will decide, not you or me.
Jesus has pronounced higher demands on us than any prophet before or after him. I think, a Christian (but also a Muslim and a Baha'i) should try to meet them as far as he can. If you don't, your faith is not real.
Jesus has higher demands for believers.. non believers not so much. This is why we know God is good and just. We know the truth if someone doesn't know the truth how can they be held to the same standard.
Luke 12:41-48
Huh? Isaiah said that our righteous deeds are filthy rags and you say out of context?
You took that verse out of context. Read the entire thing. Jesus was affirming that He was God. Don't twist my scripture please. Jesus was without sin and was the only Good human that ever lived
(archetype D) Who said that?
God.
Isaiah 64:6
6 We have all become like one who is unclean,
and all our righteous deeds are like a polluted garment.We all fade like a leaf ,and our iniquities, like the wind, take us away.
I use this one again as it's applicable to MY belief. And if you don't know what that means . Women's polluted undergarments are our "righteous works"
Ephesians 2:8–9
8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast.
but...
Our righteous acts do not produce salvation but are, in fact, evidence of our salvation
James 2:14–26
14 What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him? 15 If a brother or sister is poorly clothed and lacking in daily food, 16 and one of you says to them, “Go in peace, be warmed and filled…

Galatians 2:20
20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
2 Corinthians 5:21
21 For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.
I don't guess you will agree with any of this because it would make your religion a lie. That's ok! But don't try to make mine a lie by misusing my scriptures to prove your point.
You never see me disparage your prophet or misuse your scriptures. I could easily do both. But that's just ugly and doesn't serve any purpose than to cause division and strife.
