The Inerrancy of Scripture - Authored by God
Knowing the Bible reveals its truth to the reader.
What Isreal believed about their Messiah:
He is coming as a King to save them from their suppressors. Will be born as a King from the line of David.
A symbol of what they should expect. Predictions of who the Messiah would be. Jesus did not fit the mould of the Great and awesome God they were expecting.
Although Psalm 22 is a vision of what Jesus would experience on the cross it was not recognizable by the jews as it did not fit into their own belief system. It is with our knowledge today that we can look back at Psalm 22 and knowing the fate of Jesus see and understand the true significance of the vision of this amazing future revelation.
Psalm 22: 14 - 18
They divide my garments among them,
What Isaiah wrote here was not in line with the imagery of the Messiah as believed by the Jewish leaders at the time. Therefore for Isaiah to have been able to write this passage it could only have come from God himself. Isaiah had no grounds for this writing and the sheer perfection of the passage makes it unmistakeably the work of God.
