Living forever is easy: be born again. (It's the relationship with your Saviour that's difficult)

You only live once, but can be born twice. Then, you can live forever.

I'm a Jewish born-again Christian.

Only in the world of mathematics do two negatives multiply into a positive.

But, someone, please give me—who is born again but still so much in need of being born anew—give me the details of how to live in the waiting cocoon before the forever begins?

True repentence is to depart from evil. A return to God, seeking his grace for power to obey him.
