“But unto you I say, and unto the rest in Thyatira, as many as have not this doctrine, and which have not known the depths of Satan, as they speak; I will put upon you none other burden.” (Revelation 2:24)
The doctrine is what is taught from the depths of the heart. What is taught is not just by the mouth, but by what people do and the example that they live by. The doctrine that is being referred to here is the one taught by the false prophet spirit of Jezebel where one joins themselves to God’s people by a human relationship, (like Jezebel did in the Old Testament – see 1 Kings chapter 16 through 21) but they have an unfaithful relationship with Jesus Christ. Those who “join themselves” have something different coming up from the depths of their hearts.
“For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man.” (Mark 7:21-23)
What comes from the depths of your heart is what counts to Jesus. Jesus knows exactly what is in our hearts and he allows the difficulties and temptations of this life to show us exactly what is in our own hearts.
Jesus said that good things can come forth from us, when our hearts are right with him…
“In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink. He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)” (John 7:37-39)
If we do not have the true Holy Spirit (the one that causes us to live pure and holy) then we may take on a false religious spirit, that claims to be the Holy Spirit. This is part of the false prophet spirit of Jezebel that Jesus refers to in Revelation 2:24.
“Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.” (Matthew 7:15)
Because “inwardly they are ravening wolves” they have known the “depths of Satan” which becomes evident by what “they speak” – when they teach false seductive doctrines that they have mixed in with the Word of God. The end result is a different kind of church with people who become like them: claiming to be Christian, but they still commit sin. Because they still have sin in their hearts, they must come up with new doctrines to teach that will distract from uncovering what is in the depths of their hearts: hatred, division, and strife.
“He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctrines the commandments of men.” (Mark 7:6-7)
So I must ask you, what comes up from the depths of your heart? It will be known by what comes out of you. Jesus does not just want to clean up the outside, he wants to clean up the very depths of the desires of our heart – and he can, if we will humble ourselves to let him.
