YoYo, what you posted is a persons views of the Bible. If one want's to know what the Bible says, one should go to the source. Each individual has their own interpretations, and many twist the words to fit their own interpretations.
I learned a few years, when I want to know what the Bible says, to just read it.
Why not read 1st John 2:27 it tells us that we do not need that man teach us. The holy Spirit teaches us.
The Bible also says not to put your trust in men. That is what the JW's are doing, they are trusting man to teach them.
