'Enter into Life' in the Bible

Wherefore, if thy hand or thy foot causeth thee to sin, cut them off, and cast them from thee: it is better for thee to enter into life halt or maimed, rather than having two hands or two feet, to be cast into everlasting fire.

And if thy eye causeth thee to sin, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two eyes, to be cast into hell-fire.

And he said to him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
