Jesus said nobody knew the exact time for his return but the Father. But we could look at signs and tell when it was getting close. And then he explained what to look for. I'm in my 60's now and I can tell you it really does seem closer than it ever has been in my lifetime--if it really means a "rapture" the way it's been presented. (The word "rapture" isn't in the Bible.) I'm not sure exactly what will happen or exactly when, because I'm not sure how accurate the interpretation is that has been written about the subject. That thinking didn't come around until John Darby began pushing it in 1830.
