Mathew 24:42-43

So be alert (give strict attention, be cautious and active in faith), for you do not know which day (whether near or far) your Lord is coming.  But understand this: if the head of the house had known what time of the night the thief was coming, he would have been on the alert and would not have allowed his house to be broken into.

We are not to fear the coming of the Lord but to be about doing His work here on this earth.  The Lord doesn’t want us to give up and lose our faith because of the circumstances around us.  Jesus wants our faith to be alive and active, trusting that He will keep us safe until His return.
