Be Vigilant

Sometimes when we ask God something...He doesn't seem to answer directly. When a few of the disciples asked Jesus, "When will these things be?", they were referring to the fulfillment of events associated with the end times and the inauguration of the Messianic Kingdom when the Messiah would be King. Jesus' had a long answer that was punctuated by the phrase, "Be on guard!" Sort of a weird reply...or was it? What was Jesus trying to teach His disciples, and teach us?
