The world of Star Trek has values that can inspire people to live a moral life. However, it is not in line with the truth. The universe promotes atheism or a belief in other false gods. Gene Roddenberry was an atheist and he actually insulted the Christian faith. Why would I want to watch a show that was created by someone who is opposed to the faith and everything I hold dear?
Please keep in mind, that I used to be a huge Star Trek fan. I used to know all the episode names by heart and I owned on DVD all of the five live action series (The Original Series to Enterprise) and all of the films (up until 2016). The world of Star Trek encouraged you to better yourself even without the pursuit of money or wealth. How noble. But what about the other sins in Star Trek that it promoted? Should I ignore them?
Many of the leading heroes of Star Trek (the captains) were either agnostic (Picard) or atheists (Janeway) or they believed in false gods (Sisko).
Picard, Riker, etc. slept around with women outside of marriage. They did not acknowledge Jesus as Savior or Lord. They are unsaved men.
As for magic portrayed in Disney films:
Again, you cannot change the reality of sin just because it is in a movie or it is declared as fantasy. Again, do you not see a problem with cartoon inappropriate content movies? I am sure you do because things like that are ingrained within our culture as clearly evil. Even non-Christians can see the destructive nature of such films. But when it comes to sins like sorcery? Why does it become any less a sin when it is portrayed in a movie or book? God's Word condemns magic or sorcery. It was so serious in the OT, that God's people were to kill anyone who was a sorcerer. Granted in the NT, we are to love our enemies now, but the sin has not changed. God is not suddenly open and accepting of magic now. Magic or sorcery is still a power outside of God. It is the working of the enemy. So yes, I am saying that even a movie that portrays love, and doing good is wrong if they also promote magic. Why? Because if they get into doing REAL witchcraft by the influences of the subtle influences of these films and books promoting magic, they are going to go in the opposite direction away from God and deeper into darkness.
God is about relationships. He wants us to walk in His light and know His love, so we can love Him and others. But if we prefer darkness or sin (even in a fantasy setting), how can we walk in the light of His love? How can we serve God if our minds are serving sin or looking away from the sins of this world?
Jesus paid a great price for our sins. It is insulting to look the other way at these sin - IMO. But you are free to believe as you wish.
May the Lord and His love shine upon you in a great way today.
