Where I am going ye cannot come…

John 7:33-34 Jesus then said, “I shall be with you a little longer, and then I go to him who sent me; (34) you will seek me and you will not find me; where I am you cannot come.”

Jesus was going back into the Father in the Divine Realm which is closed to human spirits. Human spirits can only return to the spiritual realm which is their origin but never beyond that and this is the reason for Jesus saying that he was going to a place that we can not follow Him into.
