If you meant (by that stuff about unclean invading the clean) you mean the Bible is about the fight for right, then I agree.
But, isn't the worst fight going inside all, heathen and believer alike? Jesus said take up the sword, be killed by the sword. OK?
Can your mind substitute sword with hate? Take up hate be killed by hate. Mine can.
Matthew 15:
17"Do you not understand that everything that goes into the mouth passes into the stomach, and is eliminated?
18"But the things that proceed out of the mouth come from the heart, and those defile the man.
19"For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders
20"These are the things which defile the man; but to eat with unwashed hands does not defile the man.
Evil thoughts? What are they? What about false witness? Is saying, "God hates" a false witness? Let's talk about theft. When (I mean if) any holy word of God got changed the original meaning was taken away to make room for the false idea. That is theft.
How about adultery? The fleshly sin of adultery is very bad. Is spiritual adultery not worse? I am sure I have more to say, but I shouldn't feed the troll. Not you. I have a troll. What's wrong with that?
