After visiting the Temple in Jerusalem, the disciples commented on its magnificence and the beauty of the surrounding buildings. Jesus surprised them by saying, “Do you see these great buildings? Not one stone shall be left upon another” (Mark 13:2). They asked Jesus two questions in response: When will this happen? And what will be the sign of its fulfillment?
Jesus answered both their “when” and “what” questions concerning the Temple. The Temple would be destroyed during the time of that “generation,” just as Jesus had said. For it was demolished in 70 AD by the Romans. But Jesus went on to tell them even more than they had asked. He also spoke of a time of tribulation followed by his coming again. Concerning this, he gave some of the signs, but not the time. In fact, he warned that no one except the Father knows the time of his return.
Therefore, do not believe those who predict the day or hour of Christ’s return. Jesus has already told us that they do not know. Instead, follow his instructions:
1) “Take heed.” – Be prepared. Live as if he could return today. Get your affairs in order.
2) “Watch” – Stand guard. Keep your eyes open for the signs of his return.
3) “Pray” – Let prayer be the main activity of your heeding and watching.
The destruction of Jerusalem was one of the many signs fulfilled exactly according to Christ’s words. The reality that he is coming again is just as certain.
