"If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life maimed or crippled than to have two hands or two feet and be thrown into eternal fire. And if your eye causes you to sin, gouge it out and throw it away. It is better for you to enter life with one eye than to have two eyes and be thrown into the fire of hell." (Matt. 18:8-9)
Hell is such a terrible place that you should do whatever it takes to make sure you don't go there. Repenting from your sins and following Christ is the only way to avoid Hell. And if following Christ means going against what your family says, or what your friends say, or giving up your favorite sinful practice that you love to do, then its worth it. If it means giving up fame, or giving up riches, or giving up pleasure, its worth it. Even if that thing is something that is as near and dear to you as your right eye is, or if its something as useful as your right hand is to you...if it leads you into sin, then that thing, person, habit, object, or whatever it may be, however dear, you are to part with.
