Preparation
The disciples constantly questioned Jesus about matters of the kingdom, especially a physical emphasis.
One example involved their concern over the destruction of the temple, the sign of His coming, and the end of the age.
While Jesus addressed their concerns with information related to the signs prior to this event, He took them further into the events surrounding the judgment day.
He wanted them to know that something greater than the destruction of the temple was coming and the reason for teaching this truth was to prepare them for that day.
Our leadership is the same. We are to prepare others for that day.
