'Enter into Life' in the Bible

And if thy hand or thy foot is causing thee to fall, cut it off, and cast it from thee; it is better for thee to enter into life maimed or lame, than having two hands, or two feet, to be cast into the everlasting fire.

And if thine eye is causing thee to fall, pluck it out, and cast it from thee; it is better for thee to enter into life with one eye, than having two eyes to be cast into hellfire.

And he said to him, Why dost thou ask me concerning what is good? There is but one who is good. But if thou wilt enter into life, keep the commandments.
