I am sorry but I see in these scriptures that there are two kind of believers: those who believe in the spirit and they are free; and those who follow the law, they are slaves to the law. So what do you see in those scriptures?
So you say: Yes it is hard to come to terms with that terrible truth. So who was resposible for the death of Jesus?
Whenever you find yourself in Court for a crime committed, tell the Judge that you are free and not under the obligation to follow the Law. Then, wait for his verdict.
If you walk away from that Court in freedom, I'll be ready to follow you. Now, compare it with the one who is under the Law. He does not even have to go to Court, because he owes nothing and has nothing to fear. He has set things right with God, according to Isaiah 1:18,19. Check it out!
Now, with regards to who were responsible for the death of Jesus, I tell you: Those stupid jerks among the followers of Jesus who proclaimed him king of the Jews at the time when Caesar was king. Don't you read your NT? Pilate wrote on a plate the reason for Jesus' crucifixion and nailed it on the top of his cross. That was the reason for the death of Jesus: Because he had been proclaimed king of Jews. I like to watch TV Evangelism. When I see them proclaiming Jesus king of the Jews, the only thing that comes to my mind is: Behold, those stupid guys are back and don't know that they represent the ones responsible for the death of Jesus.
