What does Isaiah 59:2 mean?
John Gill's Exposition of the Bible
Ver. 2 But your iniquities have separated between you and
&c.] Like a partition wall dividing between them, so that they
enjoy no communion with him in his worship and ordinances; which is
greatly the case of the reformed churches: they profess the true
God, and the worship of him, and do attend the outward ordinances
of it; but this is done in such a cold formal way, and such sins
and wickedness are perpetrated and connived at, that the Lord does
not grant his gracious presence to them, but stands at a distance
from them: and your sins have hid his face from
that he will not hear; or have caused him to hide himself; withdraw
his gracious presence; neglect the prayers put up to him; deny an
answer to them; or, however, not appear as yet for the deliverance
and salvation of them, and bringing them into a more comfortable,
prosperous, and happy condition.
