if you could remember what it was like to be conscious when that first "sperm and egg" came together to start making YOU, then you would understand the big bang in your own experience, believe it or not
being born again is just like this but now you are conscious, which is why God gives us the body in order to recreate the big bang every time life is conceived:
the experience of being born again is when God overshadows a part in you that ignites life all over again....
like the first time
only now you are conscious of it
there is a reason it is written that the "FEAR OF THE LORD IS THE BEGINNING OF WISDOM"
the experience of NEW LIFE is terrifying
but I am speaking from EXPERIENCE now
to tell you that it does happen and it will happen to everyone just as it happened to everyone that they were born the first time without knowing when or why or where......
