WLC - Question 19
From Sensus Plenior
WLC - Question 19 What is God's providence towards the angels?
WLC - Answer 19 God by his providence permitted some of the angels, wilfully and irrecoverably, to fall into sin and damnation, limiting and ordering that, and all their sins, to his own glory; and established the rest in holiness and happiness; employing them all, at his pleasure, in the administrations of his power, mercy, and justice.
