Did God die on the Cross?

According to Muslim Apologist Ali Shabir.  Christians porverbially 'dig their own holes'
by claiming that God died on the Cross. He brings up multiple examples from his
understanding of the Christian Faith.

Shabir makes a lot of bold statements that appear to stump Christians. What i want to ask
is what does the Bible say about Jesus the Messiah and the Cross? Lets examine his
assertions.

i) Did God die on the Cross?

The Book of Isaiah specifically in the 53 chapter identifies the characteristics of the Messiah


 א  מִי הֶאֱמִין, לִשְׁמֻעָתֵנוּ; וּזְרוֹעַ יְהוָה, עַל-מִי נִגְלָתָה. 

 1 'Who would have believed our report? And to whom hath the arm of the LORD been revealed?

his suffering

י  וַיהוָה חָפֵץ דַּכְּאוֹ, הֶחֱלִי--אִם-תָּשִׂים אָשָׁם נַפְשׁוֹ, יִרְאֶה זֶרַע יַאֲרִיךְ יָמִים; וְחֵפֶץ יְהוָה, בְּיָדוֹ יִצְלָח. 

10 Yet it pleased the LORD to crush him by disease; to see if his soul would offer itself in restitution, that he might see his seed, prolong his days, and that the purpose of the LORD might prosper by his hand: 

So the 'arm' of the Lord was the Messiah  and the Lord was pleased to 'crush' him.

If the Lord's arm was chrushed.  The arm being part of the Lord did die as an Atonement for 
Sin. What Muslims fail to understand is how important the Mosaic Law was to the Atonement 
of Sin. The Mosiac Law was the foundation of the Tanakh. Sin offerings were at the forefront
of Yahweh's relationship with his people in the Tanakh. Muslims themselves do not subscribe 
to the Atonement for Sin therefore have no relation to Judaism or Christianity.

ii) God forgives freely. There is no need for atonement. 

Shabir uses the parable of the 'Prodigal Son' to illustrate his point. The parable of the
'Prodigal Son' as with the parable of the 'Lost Sheep' and 'Lost Coin' are parables that
show the Lord's pursuit for the lost. Yeshua himself also remarked that 

 "The Son of Man must suffer many terrible things," he said. "He will be rejected by the elders, the leading priests, and the teachers of religious law. He will be killed, but on the third day he will be raised from the dead." ~ Luke 9:22

Atonement was not the theme in these parables. The son sinned against his earthly father. The Sheppard lost his sheep and the woman lost one coin. Sacrificing an animal in the context
of these parables would make no sense. Shabir is breaking his own rule i.e. arriving at a conclusion and working backwards.
