Revelation 2:24-25

But unto you I say, who have not this doctrine Of Jezebel; and to the rest Who have kept themselves from being led astray by these delusions; and have not known O happy ignorance! the depths of Satan The deep arts of deceit and error practised in his kingdom, to bring in all sorts of corruption, by teaching men to account things as indifferent and innocent that are wicked and abominable; as they speak

It seems they were continually boasting of the deep things which they taught. Our Lord owns they were deep, even deep as hell; for they were the very depths of Satan. I will put upon you none other burden Than that you have already suffered from Jezebel and her adherents. Or, I will lay no new restraints or injunctions upon you; but will only confirm the laws of truth, righteousness, and goodness, given to make you free from the dominion of sin, the truest and most important liberty. But that which ye Both the pastor and the church; have already received through my gospel, as essential to true religion, and necessary in order to your pleasing God, hold fast In principle and practice, in faith, love, and obedience; till I come To put an end to your time of trial, and receive you to the heavenly paradise.
