Mar 3:24 And if a kingdom be divided against itself, that kingdom cannot stand.
Alternative: And if a rule is divided against itself, that rule cannot be established.

The general discussion is about the nature of power over adversity. Is adversity caused by a group of evil spirits who fight against good or by the nature of the universe?

What kingdom is Christ referring to here? Christ only recognizes one kingdom, one rule, the rule of the God. Those who teach that the rule of God is somehow divided between good and evil do not understand the nature of power and the nature of authority. The universal rule is not at conflict with itself.

When rules are at conflict with themselves, they are not rules at all. In making human rules, for example, we run into problems when laws can be interpreted in different ways, so broadly to make everything a crime or so narrowly to make nothing a crime. The rule cannot stand because it contradicts itself.

However, a real kingdom is not divided against itself. It has clear rules and one rule-maker. The universal kingdom Christ teaches about is just that kind of place. There is no separate authority over good and evil, but one authority over all. Can you think of another place where Christ says this specifically? That God doesn't treat the good and evil any differently at least on earth?

"Kingdom" is from basileia (basileia), which means "kingdom", "dominion", "hereditary monarchy", "kingly office," (passive) "being ruled by a king," and "reign."

"Divided" is from merizô (merizo), which means "divide", "distribute", "assign", "sever", "cut-off," (passive) "to be divided", "to be dispersed," and "to be reckoned a part."

"Stand" is from histêmi (histemi), which means "to make to stand", "to stand", "to set up", "to bring to a standstill", "to check", "to appoint", "to establish", "to fix by agreement", "to be placed", "to be set", "to stand still", "to stand firm", "to set upright", "to erected", "to arise," and "to place."
