Thyatira

Here we have a greater power of Satan and evil within the assembly; it becomes the birth-place of evil. The Lord, therefore, introduces Himself not only as the Searcher out of evil, but as mighty to judge and crush under His feet —
the Son of God, who hath His eyes like unto a flame of fire, and His feet are like fine brass {Rev. 2:18}.
There were some points in these saints worthy of commendation — faith, love, patience, zeal, and continuance in the service of God; but there was also something very false and evil in their midst. The spirit of wicked Jezebel had been terribly at work, and brought forth children. The mother of harlots is here. Her assumption had been tolerated; her adulterous and idolatrous principles taught. Some had been led away, and had fallen into her uncleanness. Their spiritual idolatry was flagrant; not only the friendship of the world, but friendship with the world. Like as in Ahab’s day, the teaching and authority of God were set aside by the idolatry and religion of the world. What is so bad as the world’s religion?
“Repent!” “Repent!” was the Lord’s command. She had had space given to her for repentance, and had repented not. Therefore said Jesus,
Behold I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. [Mark again, evil doctrine always leads to evil deeds. And I will kill her children with death, and all the churches shall know that I am He that searcheth the reins and hearts; and I will give unto every one of you according to your works {Rev. 2:22, 23}.
We see here not only the Lord’s hatred to evil, but His longsuffering, His readiness to accept a change of mind, and to restore, whatever be the character of evil.
But further. The Lord considers those who are ignorant, who
have not known the depths of Satan, as they speak,
and also those
who have not this doctrine,
and lays upon them
none other burden {Rev. 2:24};
that is, I suppose, no further trial than the common suffering that had come upon all the assembly through these evil things. It is helpful to notice how the Lord thus distinguishes persons in the same assembly.
The faithful are cheered with the prospect of the Lord’s coming, and are exhorted to hold fast till He come.
The overcomer is promised to share in the rule and reign of Christ over the nations, and to know as his own personal enjoyment what he now so ardently longs for —
the Morning Star {Rev. 2:28}.
This is now the blessed hope of our hearts, and for this we wait (Rev. 22:16).
