'Enter into Life' in the Bible

If then thy hand or thy foot cause thee to offend, cut them off and cast them from thee; it is better for thee to enter into life halt or maimed, than having two hands or two feet to be cast into everlasting fire:

and if thine eye cause thee to offend, pluck it out and cast it from thee; it is better for thee to enter into life with but one eye, than having two eyes to be cast into hell-fire.

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