He speaks of sin as a cancer which the surgeon needs to remove and he needs to be aware of all the tissues that the cancer infects. He gathers his truths about sin from both Old and New Testaments.
"Piecing together Old and New Testament passages on sin's defiling effects, we see that reprobation's impact begins and spreads in the following order:
1. to the sinners first (Romans 7:8-11)
But sin, taking opportunity by the commandment, produced in me all manner of desire. For without the law sin was dead. For I was alive without the law once; but when the commandment came, sin revived, and I died. And the commandment, which was ordained to life, I found to be unto death. For sin, taking occasion by the commandment, deceived me, and by it slew me.
2. to their progeny (next) (Exodus 20:5)
You shall not bow down yourself to them (idols) nor serve them; for I the LORD your God am a jealous God, punishing the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me...
3. to their domesticated animals (Joshua 6:21)
Even Joshua 6:17 speaks of it- And the city shall be accursed, even it and all that are in it...And they utterly destroued all that was in the city, both man and woman, young and old, and ox, sheep ann ass, with the edge of the sword.
4. to their material goods (Numbers 16:23-33)
Depart I pray you from the tents of these wicked men, and touch nothing of their's lest you be consumed in all their sins. If these men die the common death of all men, or if they be visited by the common fate of all men then the LORD has not sent me. But if the LORD make a new thing and the earth open her mouth and swallow them up with all that appertain unto them and they go down quick into the pit; then you shall understand these men have provoked the LORD. ...swallowed them up and their houses and all the men that appertained unto Korah and all their goods.
5. to their inhabited land (Leviticus 18:24-28)
Defile not you yourselves in any of these things; for in all these the nations are defiled which I cast out before you.
So even though it may be hard for us to believe that the land and houses and pets can be contaminated by the evil influence of sin, it is true. We should stretch our faith to incorporate that which scripture tells us is true and search out our ways and see if we are subtly being swept into a sin which is influencing our house, our pets, our land. Ask the Lord about it. I can see it in pets when people train them to do mean things, but the homes and the land influence must be less easy to see a manifestation of.
