The twinkling of an eye.
There is one clear message here: when Jesus comes, there will be no chance for us Christians to clean up our act and be better Christians. There will be no chance for any unsaved person to finally make that decision that they have always said that they were going to make one day. The twinkling of an eye is so fast that it will be over without anyone knowing that it happened -except afterward - and then everyone’s eternal destiny will be sealed and unchangeable. Are you ready?
