Picture Jesus and His Apostles, Peter, James John and Andrew, sitting on the Mount of Olives the first of several hills well known to Him. They must have been at an elevation high enough to view the Temple Mount. The Great Temple faced the east and sat in the center of a platform about 40 feet long, nearly 11 feet high on walls 12 feet thick. According to the the Gospel of Mark it was two days before Passover (Holy Thursday) and the Tuesday after Jesus entry into Jerusalem on Palm Sunday.
Jesus was teaching His Apostles in preparation for what was to come both in the near and the distant future. Here in Jesus teaching we also find words for our present time and guidance in answer to the question ‘What can we do?’
But concerning the day or that hour no one knows, not even the angels, nor the Son, but only the Father..,It is like a man going on a journey; when he leaves his servants in charge each with his own work… you do not know when the master of the house will return … and what I say to you I say to all: Stay Awake. Mark 13: 32-36 ESV
We each have our own work and must do what we can and are called to do as we pray and stay awake until His return.
