Jesus gave an evaluation of the churches in Rev 2-3, we would do well to heed the things He was displeased with...
4 Nevertheless I have somewhat against thee, because thou hast left thy first love. 5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
Don't leave your first love...
14 But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication. 15 So hast thou also them that hold the doctrine of the Nicolaitanes, which thing I hate. 16 Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
Get out of churchianity, the doctrine of the Nicolaitans is practiced by every church I've ever seen today, Balaams error was to teach children of God to do things that displeased the Father, invoking His wrath.
I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. 21 And I gave her space to repent of her fornication; and she repented not. 22 Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. 23 And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works. 24 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.
Again, fornication, idolatry, getting to know the depths of Satan-don't do it
1 And unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead. 2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God. 3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
Another example of churchianity, a reputation of being alive but really they are dead and dying, remember the right way, hold fast and REPENT...
15 I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. 16 So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. 17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: 18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see. 19 As many as I love, I rebuke and chasten: be zealous therefore, and repent.
the lesson here is BE ZEALOUS AND REPENT. restoke the fire inside....GET MOTIVATED, TIME IS SHORT.
