Jesus said to Nicodemus that you have to be born again, but did Jesus also explain how you get born again? I cannot think of any verse right now where Jesus explained how you get born again. Why? Why didn't Jesus directly explain all these things to the jews which Paul later on wrote about? And did Jesus require repentance from those which wanted to believe in Him? John required the people to repent but did Jesus also do this? I'm a bit confused right now.
