He was such, and probably is yet. Jude 8, 9--They "speak evil
of dignities. Yet Michael the archangel, when contending with the
devil, he disputed about the body of Moses, durst not bring against
him a railing accusation, but said, The Lord rebuke thee." Daniel
10 shows that Satan has power to oppose one of the chief angels (vv.
12, 13 in particular). In Luke 11:21 Christ calls Satan "a strong
man armed." He is "the prince of this world" (John 14:30).
