'Enter into Life' in the Bible

wherefore if thy hand or thy foot occasions thee to relapse, lop them off, and cast them away: 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 thine eye occasions thee to relapse, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two to be cast into hell-fire.

and he said to him, why do you stile me good? there is but one that is good, that is God. but if you would enter into life, keep the commandments.
