ESV 3:1 Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. 2 This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.” 3 Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”…16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Born again is an intangible idea. There is no document that can verify its reality or prove it has happened. Every detail of that new birth is internally stored in you. You are the safekeeper of your salvation through Jesus. I wonder if that’s exactly what this Word from Philippians 2:12 is speaking about? Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure.
Born a second time is a mysterious internal awareness that allows our heart to “see” the Kingdom of God has been placed within us for safekeeping. That awareness is the gift of the salvation God has worked in us. Our new birth is confirmed to us by personal growth and discovery that equips us to live a life of faith, despite our fear and trembling, because…God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
