Mark 9:45
And if your foot causes you to stumble, cut it off. It is better for you to enter life crippled than to have two feet and be thrown into hell — the foot metaphor extends the hand metaphor: the foot is the instrument of going, of movement, of the path chosen. If the path chosen by the foot leads to hell, losing the foot is preferable to following it there. The three-fold repetition of the radical-surgery metaphor with three body parts communicates the comprehensiveness of the principle: every part of the self must be submitted to the priority of eternal life.
