'Live Forever' in the Bible

I am the living bread who came down from heaven; if anyone eats this bread, he will live forever. Yes, and the bread that I will give [him] is my physical body, [so] that the world can have [never ending] life."

This is the bread that came down from heaven [i.e., Jesus is referring to Himself]. [It is] not like [the bread] our forefathers ate and [then] died. The person who eats this bread will live forever."

Then the crowd replied to Him, "We have heard from [the writings of] the law of Moses that the Christ will live forever; so how can you say, 'The son of man must be lifted up [i.e., to die]?' Who is this son of man?"

And the world, with its [physical and material] desires, is passing away, but the person who does what God wants will continue to live forever.

and the Living One. I was dead, and see, I am [now] alive forever and ever! And I possess the keys of death and of the unseen place of departed spirits.
