The first 21 verses of the chapter give coverage of the night-time conversation between our big cheese of the Pharisees, Nicodemus, and our Rabbi of Rabbis, Jesus. Interestingly, we've just read of Jesus, "... for He Himself knew what was in man." (John 2:25b) Nicodemus acknowledges that Jesus must be from God on account of the miracles, and also refers to Him as teacher.
I cannot help but notice that Jesus 'answers' Nicodemus, who doesn't appear to have asked Him any questions yet... or has he?
"What do you need to teach me, Jesus? What do I need to know from you, Rabbi? Am I missing something? I feel like I might be!"
"Well, glad you asked, although you should really know better as a teacher yourself (banter!). You will not even be able to see the new Kingdom that I'm ushering in right now, unless you are born again, my friend."
"Eh? What do you mean? Born again? I mean, I know what you're saying but it doesn't make any sense to me! Can you explain please?"
"Nicodemus, you must be born twice. The first, the natural birth, you understand full well, but the second is nothing like it, it's not a repeat of the first. It's a birth, but of the Holy Spirit. This is essential - it allows you to see and enter the Kingdom of God."
Jesus continues, "So, it's your spirit that needs a kick-start Nicodemus. You're not born, not alive in there just yet! Don't be surprised by this. Now let's talk about what you actually believe... about me! Eternal life is hanging in the balance. The big question is: can you break away from your sinful self, come into the light and receive the one who saves your soul, who stands before you?"
