William Burkitt on Luke 21:37

Our Lord had exhorted his disciples in the foregoing verses to diligence and prayer; here he sets an example of both before them. Busying himself in God's service all the day, and at night spending much time in prayer; in the day-time he was in the temple preaching, in the evening he was on the Mount of Olives praying.

Lord, what an example of indefatigable zeal and diligence hast thou set before thy ministers and members! Oh that when our Master comes, we may be found working, our people watching, and both they and we waiting for the joyful coming of our Lord and Saviour! Amen.
