I suggest you do some serious study of the Book of Revelation. Many things John saw could only be possible today because of computers. You also have to read the Book of Daniel - which corresponds with Revelation - especially the man of perdition - or as some call him, the anti-Christ. Jesus himself said that no man knows the hour of his return - not even He - but his Father in heaven - we are to watch the signs of the times. Many of the things he predicted could not have been possible in 60-90 AD.
I’ve done serious study. Have a number of books.
Put it this way...I’ve believed both ways and am just more comfortable with what I think now. It won’t keep me out of heaven because I still believe in one God and His Son who is Christ and that no man can come to God except through Jesus.
I have my reasons, but either way if I’m wrong God knows I’ll readily accept it when the time comes.
