1 Thessalonians 5:2-4
For you yourselves are fully aware that the day of the Lord will come like a thief in the night. While people are saying, "There is peace and security," then sudden destruction will come upon them as labor pains come upon a pregnant woman, and they will not escape. But you are not in darkness, brothers, for that day to surprise you like a thief.

That last bit of the text makes me think; is it a sign that you are walking in the light, if the 'labor pains' and other pointers of Jesus' return are of no surprise to you? Jesus expects us to be prepared, to be ready; he commands us to be ready. Because if we're not, he won't wait any longer (Matthew 25:1-13).
