'Eternal Life' in the Bible

And behold, one came to him and said, Teacher, what good thing shall I do, that I may have eternal life?

And every one that hath left houses, or brethren, or sisters, or father, or mother, or children, or lands, for my name's sake, shall receive a hundredfold, and shall inherit eternal life.

And these shall go away into eternal punishment: but the righteous into eternal life.
