This is about how much God loves you. For others, there was no one moment at the altar. Jesus just grew on us, and we grew up in Jesus. Lost, as in can't find my way, lost, as in groping around in a dark room. We need to know that we have been born again.
Words are imperfect.
We need a new life in a new world. If you can't see the kingdom today, then you desperately need to be born from above. Being born from above has to do with how we see things. No one can see the kingdom of God without being born from above. To be born again is to have the light turned on in a darkened room.
