"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. Be on guard! Be alert! You do not know when that time will come. It's like a man going away: He leaves his house and puts his servants in charge, each with his assigned task, and tells the one at the door to keep watch. Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. If he comes suddenly, do not let him find you sleeping. What I say to you, I say to everyone: 'Watch!' " (Mark 13:32-37)
The command of Scripture is clear. We are to "Be on guard!", "Be alert!", "Keep watch!". Jesus spoke at some length about the sign of His coming and the end of the age (See Matthew 24). As I look around today, it seems that the birth pangs have begun. Earthquakes around the world are happening at greater frequency and intensity, we are hearing of wars and rumors of wars, Israel is becoming isolated internationally, and her enemies are surrounding her and preparing for war like no other. God has promised to intervene and rescue Israel from her demise, which will ultimately bring glory to Himself.
So what are the implications of all this to you and to me? Not only are we to long for our Lord's appearing (1 Thessalonians 4:13-18) but we need to remain faithful in our service to God! In other words, we need to live our lives as if we expect Jesus to come for us today.
If you want good insight into world events and how they relate to the signs spoken about in the Bible, I would recommend you read two of Joel Rosenberg's books (Epicenter and Inside The Revolution). Also, a good blog to read on prophecy is www.prophecyupdate.blogspot.com
