Anyone who gives you a cup of water to drink because you belong to Christ, amen, I say to you, will surely not lose his reward. "Whoever causes one of these little ones who believe (in me) to sin, it would be better for him if a great millstone were put around his neck and he were thrown into the sea. 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. And if your foot causes you to sin, cut it off. It is better for you to enter into life crippled than with two feet to be thrown into Gehenna. And if your eye causes you to sin, pluck it out. Better for you to enter into the kingdom of God with one eye than with two eyes to be thrown into Gehenna, where 'their worm does not die, and the fire is not quenched.' "Everyone will be salted with fire. Salt is good, but if salt becomes insipid, with what will you restore its flavor? Keep salt in yourselves and you will have peace with one another." (Mk 9:41-50)
These saying remind the listeners that discipleship is very difficult. It demands sacrifices. These are indeed challenges to those who say that following Jesus is to find complete personal fulfilment and satisfaction. There is a war between God and the power of evil. The follower should keep in mind that he is constantly challenged to choose God.
What we are asked to give up is not something sinful. Of course we should reject sin. But we should be ready to reject something which is good and God-given (like hand, feet and eyes). These are to be rejected because they to wrong path, though they are good in themselves.
Salt purifies; so does fire. The disciples are asked to be salt of the earth. They should not lose their flavour and should not become worthless. They should live in peace with themselves and with the others. Living in peace is the flavour of the disciples of Jesus.
