be not soon shaken in mind, or be troubled

 "Some things will be happening now right before God's coming that could shake you up quite a bit. I'm referring to events that will be so dramatic that they could leave your head spinning. Occurrences of such serious nature that many people will end up feeling alarmed, panicked, intimidating, and unnerving. Naturally speaking these events could put your nerves on edge and make you feel apprehensive and insecure how I wish I could tell you these incidents were going to be a One-Shot deal but when they finally get rolling they're going to keep coming and coming, one after another. That's why you have to determine not to be shaken or moved by anything you see or hear. You need to get a grip on your mind and refuse to allow yourself to be traumatized by these events. If you let these things get to you it won't be too long until you're a nervous wreck." -author unknown

 

2 Thessalonians 2:1-2 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
