I have seen many video clips where Joel Osteen believes in universalism, which is that there are many ways to heaven and that each religion has their own way to gain access to heaven.
He also promotes the idea that homosexuality is fine and that homosexuals can also go to heaven. This is purely an evil humanistic teaching and is 100% opposite to what the Scriptures teach.
Watch this video to see for yourself.
(Please note that this video was created by Christians and portray Christian ideology... I posted this video simply to expose the false doctrines that Joel Osteen teaches that not even the Christians accept... Please note that I do not accept the Christian teachings either, but only Scriptural evidence)
Do you really want to follow anyone who promotes these ideologies?
