God the Son, Jesus Christ was born into our human race for our salvation. Can the Son be in many places at once? I think so, as God is Omnipresent. But does God have only one central presence? One for each of the three persons? Interesting to consider.
I am sure God made life on other worlds, other people. But what if they need salvation, what do they have? Can the Son also manifest there at the same time as he for example walked the Earth, or is he only free now? Or do they have some other means?
I'd say some other worlds have become paradises.
Looking at our world, Dolphins and Elephants are highly intelligent. Under other circumstances Elephants could have been sentient, dressed, made tools, done art and even sinned and needed a saviour. As they are, I think they go on to live in an afterlife in a paradise. It must be that they cannot knowingly sin.
So I open discussion about the Son and his presence and other worlds of sentient creatures.
The Bible does not talk about how Christ will redeem... "worlds" (plural) and how all of them will live on the New Earth. Nor does it say if these other worlds will be condemned at the judgment, either. This is merely the influence of Science Fiction. The Bible tells us not to love the things of this world (See: 1 John 2:15-17). Also, those who have encounters with aliens sometimes smell brimstone, just as those people who have ghost encounters sometimes smell brimstone. Brimstone is associated with hell in the Bible. That is just one coincidence. Another coincidence is that whenever somebody gets involved in the occult, they are more likely to have alien encounters or alien abductions. Another coincidence is that these aliens or UFO saucer phenomenon can be cast out in the name of Jesus Christ.
I remember one time, I watched a video by a Pastor who referred to how the word "owl" can sometimes refer to demons in the Bible. The Pastor said that the shape and color of the eyes of owls matches up with the shape and color of the eyes of the ever popular grey alien that people see when they have alien encounters (i.e. black almond shaped eyes). At the time, I didn't think much of it. But then months later, I seen a trailer for a movie called "The 4th Kind" and it was a movie about alien encounters. What was disturbing is that they showed owls in the trailer with them morphing into these grey aliens. In the trailer, it looked like these people were being possessed, too. Very disturbing movie trailer.
I used to be a huge fan of Star Trek, and Science Fiction. I collected the five major series of Star Trek (at the time) on DVD from the Original Series to Enterprise (and knew many of the episodes by name). I even went to Star Trek Experience in Las Vegas (When it existed) several times, and I had been to one Star Trek convention. I even played the role playing game with my ole buddies. But after seeing the many sinful things being pushed within movies these days, I put away general sinful secular movie watching, and I now only watch Christian movies, educational documentaries, and a few occasional wholesome good family value romance films (to watch with my wife).
Another problem I had with Star Trek is that it promoted Atheism and Evolution.
Granted, there were a few episodes and exceptions to this, but they were not common (Unless you consider DS9's storyline on the alien like gods being like of the Bible - of which I do not agree with). The creator of Star Trek (Gene Roddenberry), was strongly against Christianity and he even insulted God and the Bible.
Most of the time, people love to fantasize about aliens out of their love for Science Fiction. But most of your Science Fiction pushes sinful things within them. So my encouragement to you is get in the Bible and ask God to show you the truth on this, and He will. I know for a fact that aliens are a part of one of the many demonic deceptions in these last days. So my encouragement to you, don't fall for it. Get in the Bible more and put away your either your love for Science Fiction or your love for the fascination of UFO encounters.
People ask, then why did God create the universe so big if there is no life on it?
Because God is big and He does things big and magnificent.
For God has even named all the stars.
I hope this helps and may God bless you today.
