Part of the reason some are "rejecting Jesus" and the entire New Testament is because they never understood/comprehended the NT, in the first place. (Some have admitted they've never even READ the Bible, except for a few snippets; yet they're in counter-missionary Facebook groups, mouthing off about how they now "have finally found the truth.")
Facebook (actually, the entire Internet) reeks with people who believe themselves to be teachers when, in fact, they have all sorts of misunderstandings about Scripture. Take this comment, for instance:
"Why believe Paul when he's clearly teaching contrary to Yeshua's pro-Torah message?"
GARBAGE! That statement is completely false! Paul, NEVER taught against Torah! Please read these two articles to get an inkling as to why that statement is totally ludicrous. Paul’s writings have been misinterpreted and What does Galatians really say?
Internet (especially Facebook) "teachers" are leading each other astray. So, instead of clinging to what others tell you, why not read the ENTIRE BIBLE yourself, so that you can at least be knowledgeable enough to be able to discern good from bad teachings?
