you are misinformed then buddy. They don't practice that heaven is full but that only a small amount get into heaven. When did they prophesy the end of the world? They celebration of the holidays make sense to me because really, they are pagon rituals for pagon God and it seems pretty much a slap in God's face to praise those things imo. I'm a prove your point scripturally if you practice religion, otherwise those view are nothing more than your own wishful thinking. Did they show you anything from the scriptures to prove their point or did they just say blah blah blah and stop?
