Jesus says to the Pharisees that he is going away to somewhere that they cannot follow. He is saying that He is divine and that they belong to the Earth. He says that He will die in their sins unless they do not believe in God, then they will die in their own sins. Jesus also says that God has never left him. Jesus gained disciples by preaching this. As disciples of God we know that He will always be with us and love us. God will always forgive our sins and stand by us.
