Standing firm on Doctrine

An encouragment from Paul for the believvers in Thess., to stand firm on their truths he had told them in person and in his letters. Don't get off the path to the truth, following false teaching that was going on at the time. Like you missed the rapture or you are in the middle of the tribulation etc. keep looking to the Scritpures - what does the Bible teach not some one on the internet, radio or TV that is telling you something that does not line up with the Bible
