Matthew 12:43 When the unclean spirit is gone out of a man, he walks through dry places, seeking rest, and finds none.
The word “When” refers to an inevitable condition of the human heart, by which a person’s mind is to a lesser or greater extent, naturally under the domain of one or more devils, and unless Christ serves them an eviction notice, that person remains under their jurisdiction, for all intents and purposes. That’s why the word “When” is used instead of “If”.
If it was just a mere possibility Jesus was referring to He would have used the word “If”, and therefore, it would go something like this: “If the unclean spirit goes out of a man”. The Weather channel does not speak of Hurricane season as an “If”. It says “When” hurricane season begins, for what is being referred to is an inevitable fact of life. You ask any Floridian in their right mind if hurricane season is a mere possibility, or whether, come June 1st, or even before, you could expect strong winds, and heavy rain.
Down here in the Sunshine state it is sun in the morning, with afternoon thunderstorms. It’s not an “If” it’s a “When”. Thus, when Jesus opens with the word “When” He is referring folks to a grave condition of the human heart, by which it is dominated by an unseen person who will never leave on his own. It does not matter how many good habits and talents folks might have cultivated, and it does not matter if one has a good credit score, is well educated, or has lots of cash.
Matthew 12: 43 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and finds none. 44 Then he saith, I will return into my house from whence I came out; and when he is come, he finds it empty, swept, and garnished. 45 Then he goes, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
May The Lord add His blessing to the study of His word. God bless!
