What did you have to do, Jesus is asking, with being born? Did you work hard to earn the privilege of being born? Did it happen due to your hard work and skillful planning? Not at all. You don’t earn or contribute anything to being born. It is a free gift of life. And so it is with the new birth. Salvation is by grace — there are no moral efforts that can earn or merit it. You must be born again.
