'Enter into Life' in the Bible

"If your hand or your foot causes you to stumble, cut it off and cast it from you. It is better for you to enter into life maimed or crippled, than to keep both hands or both feet and be cast into the everlasting burning.

"If your eye keeps causing you to stumble, pluck it out and cast it from you. It is better for you to enter into life with only one eye, than to keep both eyes and be cast into the Gehenna of fire.

"Why do you ask me about what is good?" asked Jesus. "There is but One who is good. But if you want to enter into life, keep the commandments."
