Commentaries:
A Christian's potential is so fabulous that he must do whatever he can to ensure it. No matter how important they are to us, we must abandon any worldly attachments, friendships, and employments that will lead us into sin, or we will receive eternal judgment. Of course, Jesus' illustrations of cutting off a limb or plucking out an eye are not literal, but He wants us to understand the stakes. It is far better to attain to eternal life without enjoying the pleasures of sin than to enjoy them here in this life and be lost. Thus, Jesus emphasizes that we must remove temptation and avoid sin at all costs.
