What would the Spirit saith "unto the churches" in Revelation, if Galatians is written "unto the churches"?

I believe Jesus Christ had a lot to say. John 3 16. It's about Gods love for his people and possibly anger at some within the church. Jesus spoke to your average joe not accepted by the church. He is speaking to different churches about different things. It's really not contradictary at all. I believe he can save or destroy anybody he wants to. I believe, it's not who you think is saved, rather who he says. Also he does talk about if the light in you is darkness how great is that darkness.
