What if Jesus had failed?

[Drich]

If the mechanical process was all that was required, then what happens to the souls of men like David, (a man after God's own heart) Abraham, Isac, Jacob, Moses, Daniel, and everyone else not under this new covenant/mechanical/Christian scrifice???

I agree that David was a man after god's own heart. He certainly acted the part.

In any case, are you saying that god cannot forgive sins without a physical sacrifice, or that he refuses to do so?

Also, those who were under the OT laws (Moses, David, etc) presumably performed the necessary sacrifices with the proper frame of mind and were cleansed by the final cost of sin, which is death. Why would they need Jesus to atone for sins that they paid for, possibly twice?

Abraham, Isac, Jacob, Joseph, Nathaniel, and on and on were not under the law yet they still sinned... Not to mention The penality for adultry was death of the adulturers no animal in under that covenant could cover that sin. A sin both David and soloman were guilty of...
