Isaiah has often been called ‘the fifth gospel’ because of the great detail in has in depicting the life of Jesus. When we read through Isaiah 53 I think we can see that this is justified as it depicts the suffering and death of the Messiah, not just the physical aspects but why he died.
“Surely he took up our pain and bore our suffering, yet we considered him punished by God, stricken by him, and afflicted. But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed. We all, like sheep, have gone astray, each of us has turned to our own way; and the Lord has laid on him the iniquity of us all.” (Isaiah 53:4-6 NIV)
