He says I will not drink again, but nowhere does Scripture say that He drank from the cup once He blessed it and spoke of it as His blood. Look again at the passage...
in Matthew, He blessed it and GAVE IT TO THEM saying....
in Mark, and He took the cup and He GAVE IT TO THEM.....
in Luke, 17 And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves:
and then AFTER supper, when the meal was ended, He took bread and likewise the cup.
It does not say it, no matter how badly one may want it.
Whatever makes you feel better Jvette. That still leaves Him causing others to sin.
