I've always had a problem with Mark 9:43 (and the similar foot/eye verses).
If your hand causes you to sin, cut it off. It is better for you to enter into life maimed than with two hands to go into Gehenna, into the unquenchable fire.
If my hand were to cause me to sin, then it would have free will and do whatever it wanted. My hand does not have free will, and thus cannot sin. It cannot cause me to sin either.
If I wanted to steal something, but I have no hand to accomplish that sin, then I have still sinned through my desire.
Since I do not hear this point of view expressed - I assume that I'm out in left field on this one. Can someone please let me know where I got lost? Many thanks!
