We don't hear that enough...Jesus told us to repent. On a side note; I am blown away by the number of Christians (especially women) who believe they will be 'raptured' before things get too rough.
The next thing in the sequence is invasion. We best get our act together soon. Preferably before the invasion. A little humility would go a long ways these days.
As for the rapture thing, preachers teach what people want to hear these days. Not scripture. Read Mathew 24 there is this little thing about the sun turning black and the moon turning red before his return. Then read Revelation 6, on the sixth seal...
THEN read about the rapture, next couple of paragraphs.
