'Eternal' in the Bible

And behold, a certain legal expert stood up to test him, saying, "Teacher, what must I do so that I will inherit eternal life?"

And I tell you, make friends for yourselves by means of unrighteous wealth, so that when it runs out they will welcome you into the eternal dwellings.

And a certain ruler asked him, saying, "Good Teacher, [by] doing what will I inherit eternal life?"

who will not receive many times more in this time and in the age to come, eternal life."
