Please clear my doubt raised by Christians

[Peer Kristijan]

Christians say that, since God is just, he must surely punish sins. There must be, therefore a redeemer for those sins. Jesus was that. How would you guys respond?

Why MUST He do anything?

There is no MUST for God.

The Qur'an says very clearly that divine justice will be replaced by divine mercy. [6:147, 7:156].

Mortals like you and I do not have what it takes to decide for God's actions.

God sent God down to make God die and redeem the sins for God. Makes sense that’s why 

[Revert1963]

How would it be just to let Nabi Issa pay for other peoples sins?

As far as I understand it There are three types of sin. The Sin we do against others, the sin we do against our selves and the Sin we do against God.
The two latter God will forgive if we truly repent and stop doing it again.
The Sin we do against others God will forgive to the extend that we our selves forgive the sins others has committed against us.

So the redeemer is the same person as the judge?
