Reniaa with all due respect how can you equate 1 Thessalonians 2:13
With “The biblie testifies to itself those that don’t believe in it are fools to themselves and it’s truth”? Paul's words don't even come close to meaning that in the text you quote.Taking words out of context or trying to have them say something other than what is meant like you just did is showing disrespect for the author. That verse is not open for interpretation by any stretch of the imagination.
Regarding 1 Thessalonians 2:13
Paul may think that what he’s preaching is the word of god, the readers may believe it’s the word of god, but nothing is proved by this self proclaimed truth. Just because I may say something is the truth and the person that listens believes me, doesn’t automatically make it the truth. It has to be provable especially when doubted. I don’t know of any religion that claims not to have the truth, Christian or others. Au contraire everyone speaks in the name of their god or gods. My time in the JW’s taught me one valuable lesson in life, doubt everything religious and don’t rely on faith.
