These are good thoughts.Had Paul read the Word of God prior to his trip to Damascus? Having so read, and assuming, he assumed he understood the Word of God was he not in reality blind and in ignorance to the Word of God.
Are we not the very same. By the will of God, do we not have to have the scales of blindness removed from our minds in order to know the truth of the Word of God?
When was the blindness of Paul's mind removed? 9:15 or 9:18?
It must also be remembered that to the Jew, salvation and communion with God took place through the offices of the priests, and more particularly the offices in performance duty at the temple.
Saul (Paul) was about as politically, socially, economically, and theologically tied in as an elitist of each area as one could become. This is part of the reason that hardly had he experienced conversion and the rulers of the Jews gathered seeking to kill him. He held great influential power. He could also out debate all Jews concerning the Scriptures (Jews enjoy debate of Scriptures) as validated by him entering multiple places of Jewish worship and leading untold numbers of the priests and leaders to the Christ.
Prior to the road to Demascus, Paul stumbled over the very problem the Apostles did (prior to the resurrection) by rejecting the thinking that the Messiah would die. Remember the anointing done at Simon the leper’s house?
The Jews were temple bound. It was there way to be redeemed, and the leaders held authority of inclusion and exclusion to the temple worship. To the typical Jews temple access was the ability to enter as sinless the kingdom of God. This is why Jesus said that the leaders prevented those entering from entering in Matthew.
A member of the BB misappropriated this verse to support the failed view of partial human ability. It is erroneously taking the verse out of the context of who and the cultural aspects of their thinking.
