Keep Watch

How do we motivate Christians to Christian living?  One way is to convince people that Jesus is returning at any moment.  But what Jesus has revealed here and what the rest of the Scriptures support and teach is that Jesus' return is not yet imminent.  We are still in the time of the birth pains, not yet at the end of this age.  What, then?  Can we kick back and relax, live it up in this age while we wait for the anti-Christ to appear?  Why do we need to keep watch?  How do we keep watch now?  From Matthew 24:36-51.
