The ‘cut-off-your-hand’ extremity that Jesus instructs us to take will lead us to do things that would be ridiculous for others to do. But we take extreme action, to win the war in our own hearts, and don’t worry too much about what other’s may think in this regard.
Better to not have a facebook account, than live a life gripped by envy and comparison.
Better to be teetotal, than live a life enslaved to alcohol.
Better to not own a home, than live a life of captivity in a golden cage.
Better to not have an internet connection, than live a life addicted to online porn.
All four of those might be ridiculous actions for you to take, both in your opinion and in actuality.
But disciple, you’re doing something extreme to fight the sin that’s crouching at your door aren’t you?
