When the disciples showed Jesus the impressive Temple of God in Jerusalem, He prophesied of the temple’s destruction,
“So they asked Him, saying, ‘Teacher, but when will these things be? And what sign will there be when these things are about to take place?’” (Luke 21:7).
Then He answered their questions about the destruction of the temple, which happened in AD 70 by the hands of the Romans. The disciples wanted to know when it would happen, and what sign or signs would indicate the coming destruction. Therefore, as you read His answer, keep in mind what they had asked, and it will help you to know what He meant in His answer.
