Oh believe me, I hold what Jesus said dearly.For example, when He spoke of cutting off your hand or gouging out your eye to enter Heaven an amputee instead of Hell whole, people say, "He was only joking. Hyperbole." Yet it seems to me He was rather pointing to the truth that the law required perfection. This statement cannot be said to a post-cross believer as their perfection is found in Christ, being made perfect. This, however, can be said to a man under the law, to make him realize perfection is required and such a man would see his need for Jesus.
You see, it isn't about ignoring Christ's words, but properly applying them and putting them in context.
The part that "grace" believers leave out is - "if thy eye/hand offend thee".
Jesus was perfectly serious that if something about you offends to the point that it would result in you being cast into hell forever, it would be far, far better for you to do without that temporary thing than to suffer such an unbearable eternal fate. He was stressing the utter seriousness of avoiding hell.
"Grace" believers, of course, twist this around to make it say something entirely different than what Jesus meant.
