That brings about a question in my mind. If the angels are sinless...do they not have free will? Just asking...curious because satan was the greatest of the angels, he and a third of the angels were cast out of heaven for sins against God...right?
Freewill is the nature of this world and angels have it too, as you’ve just demonstrated.
The Angels have free will, but, as purely spiritual beings, exist outside of time. They make their choice to love and obey God once, for all eternity.
He's 2/3's right...
Revelation 12:4 English Standard Version (ESV)
His tail swept down a third of the stars of heaven and cast them to the earth. And the dragon stood before the woman who was about to give birth, so that when she bore her child he might devour it.
