The angels are his angels, angels created by the Son of Man. They are, as it were, raring to go.
Do you tell yourself that God will never judge the world and that sin has no consequences? Do you think that you can enjoy the pleasures of sin without paying for what you do? Has your conscience been beaten into silence, or into an occasional whimper only? Do not deceive yourself. God will rouse himself from his sleep, and show that nothing has escaped his attention. He will cleanse his kingdom in which you are dwelling as an imposter. He knows the difference between those who are his and those who are planted by the enemy. Though the difference between them is sometimes unclear to us, the Lord knows them that are his. Make every effort to enter fully into his kingdom, for at the end of time, his kingdom will stand and all other kingdoms will be cast down.
