Jesus spoke in Revelation chapter 2:
17 But the one whose heart is open let him listen carefully to what the Spirit is presently saying to all the churches. To everyone who is victorious I will let him feast on the hidden manna and give him a shining white stone. And written upon the white stone is inscribed his new name, known only to the one who receives it.
19 I know all that you’ve done for me—your love and faith, your ministry and steadfast perseverance. In fact, you now excel in these virtues even more than at the first. 20 But I have this against you: you tolerate that woman Jezebel, who calls herself a prophetess and is seducing My Loving servants. She is teaching that it is permissible to indulge in sexual immorality and to eat food sacrificed to idols. 21 I have waited for her to repent from her vile immorality, but she refuses to do so. 22 Now I will lay her low with terrible distress along with all her adulterous partners if they do not repent. 23 And I will strike down her followers with a deadly plague. Then all the congregations will realize that I am the one who thoroughly searches the most secret thought and the innermost being. I will give to each one what their works deserve. 24 But to the rest of you in Thyatira who don’t adhere to the teachings of Jezebel and have not been initiated into deep satanic secrets, I say to you (without laying upon you any other burden): 25 Cling tightly to all that you have until I appear. 26 To everyone who is victorious and continues to do My works to the very end I will give you authority over the nations 27 to shepherd them with a royal scepter. And the rebellious will be shattered as clay pots— 28 even as I also received authority from the presence of My Father. I will give the morning star to the one who experiences victory. 29 So the one whose heart is open let him listen carefully to what the Spirit is presently saying to all the churches.
The above passages are critically important for Jesus is warning us. I suggest dwelling and meditating on these passages.
