Isaiah 53 Verse 10

[RabbiO]

But if a Jew really humbles himself, he will say, "God I need your help, I can't get rid of the sin and circumcise my heart, do with me as you see fit," and God will forgive his sin. Maybe then, maybe later, God will lead him to see the truth, and show him how God was able to forgive his sin, with or without animal sacrifices, and he will believe in the one who did the real Yom Kippur once for all.

If you want to debate with someone who on some level identifies as a Christian then I suggest the two of you find some other forum to do so. 

As to, among other things, the last paragraph of your post that is naked proselytizing and out of place here. If that is how you expect to spend your time here might I suggest that this would be a good time to exit this forum. Proselytizing is unwelcome here.
