Jesus answered him, "Most assuredly, I tell you, unless one is born anew,{The word translated "anew" here and in John 3:7 (anothen) also means "again" and "from above".} he can't see the Kingdom of God."

 So then belief in Jesus has these three elements--belief that God is our loving Father, belief that Jesus is the son of God and therefore tells us the truth about God and life, and unswerving and unquestioning obedience to Jesus.
