Because they don’t understand the Bible.
If something is written in a foreign language and then is translated into English. Then you go to a church and listen to the English words like, “a snake came down a tree.” Then the pastor explains it by saying it’s a snake coming down and tree. And you say, I know what a snake is and tree is.
This isn’t an interpretation of the meaning of the words. It’s just being read to you literally.
Yet the Bible says over and over it’s a parable and a riddle and only the Seeker finds it.
