I'm not clear here: are you saying all those who believe in UFO experiences lose their faith? Or all those who believe the have experienced UFOs lose, or have lost, their faith?
No, not saying that...I am saying that there are many in the NEW, though not really new, New age Spiritual Movement and the like... who have integrated UFO and space aliens into their beliefs and are promoting this to Christian believers...and using Christian elements to attract them. Once they are “hooked” and get into things like transcedental meditation or out of the body experiences, where they believe they are seeing Christ..and or fighting heavenly battles for Him,...it is a difficult thing to reason with them when the experiences they are having appear so real to them...and they believe they are real and of God. In the process of indoctrinating these people they loose their ability for critical thinking as the levels of “enlightenment” or “acession” thru various relmns rituals or practices are so intensive. It’s actually pretty awful but there are many “teachers” on line, where this is mostly happening and why it is spreading so rapidly, who “walk” them thru these practices assuring them that their fears are misplaced etc.
These are Christians who have been seduced and deceived...as with all cults...they use Christianity to do this. Eventually, if they remain in this..their true biblical beliefs become twisted....because this movement is very good at hoodwinkling people. Thus they do shipwreck their faith..they soon believe more of the nonesense then they do the truth...”You cannot serve two masters” one will become dominate and generally these experiences will win over “faith” as we know it to be.
