Except for occupying Roman soldiers, and tourists, who but Jews lived there to do anything? Jesus himself was a Jew and so were all of the apostles. Both the perpetrators and the victims, if you will.
It was every sinner that sent Jesus Christ to His death, which includes every person, which includes the Jews, and you, and me.
And the relevance of this to Muslim Mass Murder today is...?
No it was not. Neither was it the Romans or any other group or person for that matter. Were you aware that Jesus knew about all of the twisted lies, blaming, blind and unfounded accusations and persecutions that all the world and satan would let loose concerning His death? And true to His unyielding, unbending, unbreakable, and unbearable character trait and nature of Love, He gave the answer to any and all who care to listen to him. And He put it in writing for all generations to come, even before it happened, even before you yourself asked of your own free will. Jesus’ own powerful yet simple answer brings peace, where there is discord, destroys blame where there is finger pointing hypocrisy, and unfathomable conquering Love where people think only hate and vengeance could possibly rule. Here is Jesus’ answer to your question in his own words from the Holy Scriptures... John 10:17-18 17 The reason my Father loves me is that I lay down my life - only to take it up again. 18 NO ONE TAKES IT FROM ME, BUT I LAY IT DOWN OF MY OWN ACCORD.(emphasis mine) I have authority to lay it down and authority to take it up again. This command I received from my Father.
What saith the Scriptures? 10Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole. 11This is the stone which was set at nought of you builders, which is become the head of the corner. 12Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. 13Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus. 14And beholding the man which was healed standing with them, they could say nothing against it. 15But when they had commanded them to go aside out of the council, they conferred among themselves, 16Saying, What shall we do to these men? for that indeed a notable miracle hath been done by them is manifest to all them that dwell in Jerusalem; and we cannot deny it. 17But that it spread no further among the people, let us straitly threaten them, that they speak henceforth to no man in this name. 18And they called them, and commanded them not to speak at all nor teach in the name of Jesus. 19But Peter and John answered and said unto them, Whether it be right in the sight of God to hearken unto you more than unto God, judge ye. 20For we cannot but speak the things which we have seen and heard. 21So when they had further threatened them, they let them go, finding nothing how they might punish them, because of the people: for all men glorified God for that which was done. 22For the man was above forty years old, on whom this miracle of healing was shewed. 23And being let go, they went to their own company, and reported all that the chief priests and elders had said unto them. 24And when they heard that, they lifted up their voice to God with one accord, and said, Lord, thou art God, which hast made heaven, and earth, and the sea, and all that in them is: 25Who by the mouth of thy servant David hast said, Why did the heathen rage, and the people imagine vain things? 26The kings of the earth stood up, and the rulers were gathered together against the Lord, and against his Christ. 27For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together, 28For to do whatsoever thy hand and thy counsel determined before to be done.
