New Defender's Study Bible Notes
2:2 works. Compare I Thessalonians 1:3—“work of faith, and labour of love, and patience of hope.” However, their love was beginning to wane.
2:2 are not. These false apostles were also of great concern to Paul (II Corinthians 11:13-15). John had no doubt warned the Ephesians to “try the spirits whether they are of God,” for they might well be “false prophets” (I John 4:1). They had done just that, and Christ commended them for it.
2:13 Satan’s seat. “Satan’s seat” is literally “Satan’s throne.” This may be a reference to the great altar of Zeus at Pergamos, but there is also some evidence that the priesthood of Babylonian idolatry had moved to Pergamos when Babylon fell to the Persians.
2:13 Antipas. “Antipas” means “against all.” Although Antipas may have been an otherwise unknown martyr (i.e., “witness”) at Pergamos, the Lord may have included his name here to represent all His faithful witnesses who take a clear stand for Christ “against all” the forces of Satan, even at the possible cost of martyrdom.
