'Enter into Life' in the Bible

"And, if your hand or your foot causes you to stumble, cut it off, and cast it from you; it is good for you to enter into life maimed or lame, rather than having two hands or two feet to be cast into the eternal fire.

"And, if your eye causes you to stumble, pluck it out, and cast it from you; it is good for you to enter into life with one eye, rather than having two eyes to be cast into the Hell of fire.

And He said to him, "Why do you question Me concerning the good? One is the Good. But, if you wish to enter into life, keep the commandments."
