Isaiah 64:10

Thy holy cities are a wilderness, Zion is a wilderness, Jerusalem a desolation.

The desolation of the holy cities and of Zion and Jerusalem belongs to a wider summons addressed to God's people to listen to His reproofs and enter into thorough consecration. That summons presses with special force upon those entrusted with positions of responsibility. Heeding it means putting away complaining and putting away evil work. Such putting away clears the way for God to manifest His power in the conviction and conversion of souls.
