'Enter into Life' in the Bible

If your hand or your foot causes you to stumble, cut it off, and cast it from you.[note: idiom meaning to stop doing a sin] It is better for you to enter into life crippled or maimed, rather than having two hands or two feet to be cast into the eternal fire.

If your eye causes you to stumble, pluck it out, and cast it from you.[note: idiom meaning to stop doing a sin] It is better for you to enter into life with one eye, rather than having two eyes to be cast into the fire of hell.

He said to him, "Why do you ask me about what is good? No one is good but one. But if you want to enter into life, keep the commandments."
