You stated: "So, if Jesus did not die on the cross you would disown him, yes?"
You tell me what you think....If Jesus didn't die on the cross and if me being a believer in God and knowing that I will die in my sins because I'm not perfect enough to stand in God's presence... knowing that Jesus didn't die on the cross and animal blood sacrifices were not enough.... then compare it to....
If I was muslim and thinking if I only worked hard enough to go to heaven and died and found out I had worked my whole life and sacrificed so much to only find that I was going to hell. You tell me which one is going to be upset? The one who knew all along they were a sinner and needed a savior that could actually save them, or the one who worked so hard on saving one's self?
