Angels as an Instrument of Judgement (Isaiah 6:5)
Though not always, angels were many times sent out for judgement
Sodom and Gomorrah (Genesis 19:1-11)
Was their only sin homosexuality?
No, they were prideful, lazy, stingy, and haughty (Ezekiel 16:49-50)
What makes homosexuality so abominable? Answer: It is against nature (Romans 1:26-27)
But just as there is mercy for these sins, there is mercy for the homosexual (1 Corinthians 6:9-11)
