Does the justice of Allah require a sacrificial payment or an off-setting good deed to atone for sin, or can He graciously forgive sin straight away with only the sinner asking Him for forgiveness in sincere repentance?
First to clarify the definition of 2 important words:
Atone - to make amends or reparation, as for an offense or a crime
Forgive - to grant pardon for or remission of (an offense, debt, etc.)
From a Christian perspective, does Allah forgive (cancel, erase) a Christian of his sin or is his debt of sins atoned (paid, compensated) for by Jesus' Blood? One may see it as nit-picking but if a debt is forgiven then it is cancelled as a free gift without any payment from anyone. I see an atonement as a payment to offset or substitute for that debt even if the one to whom the debt is owed makes arrangement for its payment. If the debt is to Allah, then I don't see how He can pay or sacrifice Himself for something that is owed to Him. It makes more sense that out of His mercy and with a figurative sweep of His hand, then the sin debt vanishes.
A human repents by feeling regret, asking for forgiveness and intending to not repeat the sin, but how does he make amends? In Islam we make amends or atonement for our sins by offering additional charity, fasts or prayers, but are those deeds required for forgiveness? We have the concept of offsetting sins with good deeds akin to a balancing scale of justice, but this is seen as 'earning' one's salvation. Isn't Allah able to forgive sin with only repentance or is an atonement or payment for sin debt also required?
I personally see that Allah is merciful and forgiving along the lines of "...those who remember God and implore forgiveness for their sins if they do something shameful or wrong themselves - who forgives sins but God?..." (Qur'an, 3:135) If Allah can forgive sins, doesn't that completely negate the basic premise of Christianity - Jesus' supposed sacrifice on the cross as the only possible means of reconciliation with Allah?
I read through this thread, with many strong opinions expressed, but thought I would start with the original question/comment.
While I am a Unitarian Universalist, I have studied Christianity, but I still have a hard time with the whole forgiveness/atonement thing.
My faith tradition does not include punishment for sin, because we don't believe in sin.
When you asked why, since Christians say Jesus died for their sins, why do they need saving, I believe that is a very valid question, and one my predecessors asked centuries before me, and answered it by establishing a belief in universal salvation.
In other words, Unitarian Universalism teaches Allah will bring us all back to him, and nothing we do or don't do will alter that. For that reason, we believe we are duty bound to help others, make the world a better place, etc., but not because we are accruing "credits" for heaven, but rather because it is the right thing to do.
So, when you first asked whether Allah may forgive a sin without atonement, I would have to answer it is irrelevant, because we will all return to him anyway.
