I was also struck by the line where he says, "I have other sheep that do not belong to this fold. There also I must lead, and they will hear my voice…." Honestly, this had me thinking about species that are alien to Earth. Being God, Jesus is not limited to just our planet, and He would not leave other beings unprotected from the machinations of the devil and his minions. This gives me hope for heaven in that, not only would I have a chance to meet with souls from all over the Earth and throughout time, but also from distant stars in galaxies too far away for us to even know of their existence.
For a person who dreams of science fiction experiences, this hope of the interconnected heaven is one that brings me profound joy.
