The 101 Bible Study focuses on Isaiah 22.
“Grief came to [Isaiah]. . . because the inhabitants of Jerusalem, who should have acted as a holy priesthood, had, by their sin and their generally careless attitude, themselves been the cause of the city’s downfall. When calamity comes to the Church, every Christian must feel that calamity as though it were his own. The hymn writer has accurately stated the matter:
For her my tears shall fall,
For her my prayers ascend;
To her my cares and toils be given,
Till toils and cares shall end.”
(E. J. Young, The Book of Isaiah, Vol. 2, p. 92).
“When we think of the power of the key, we are reminded immediately of what Christ said to Peter: ‘I will give you the keys of the kingdom of heaven’ (Mat. 16:19). Christ is ‘the true one, who has the key of David, who opens and no one shall shut, who shuts and no one opens’ (Rev. 3:7). Through the offices, Christ allows His church to serve as steward. Isn’t this an awesome policy for a world writhing in pain?” (C. Vanderwaal, Search the Scriptures, Vol. 5, p. 27).
