@ jhine - I should have phrased it as, "the corruption in the Christian congregations worldwide" - as can be be seen by Jesus' words to them in Revelation chapters 2 & 3.
As for inner/interior rooms -
(Proverbs
24:4) "And by
knowledge will the interior
rooms be filled
with all precious and pleasant things of value."
Where
is knowledge retained and stored? In the heart & mind?
(Isaiah
26:20) "Go, my
people, enter your inner
rooms, And shut
your doors behind you. Hide yourself for a brief moment Until the
wrath has passed by."
