A divided household falls ...
Now he was casting out a demon that was mute. When the demon had gone out, the mute man spoke, and the people marveled. But some of them said, “He casts out demons by Beelzebul, the prince of demons,” while others, to test him, kept seeking from him a sign from heaven. But he, knowing their thoughts, said to them, “Every kingdom divided against itself is laid waste, and a divided household falls. And if Satan also is divided against himself, how will his kingdom stand?
I once spoke to a young couple (who were Jehovah Witnesses) that told me that Satan was involved in miraculous healings. These embraced the same error that some in Jesus day held. These simply did not understand the nature and the mission statements of spiritual kingdoms. If they did they would realize that demonic forces are never portrayed in the bible in a way in which good is used to do create evil. Jesus' answer to evil was to exorcise it.
On the flip-side I know of many people who seem to always be seeking a sign from heaven. It reminds me of a time in 1976 when my first wife wanted to be healed of diabetes and went off her insulin as "an act of faith". As she became ill God spoke to the both of us through the scriptures about the foolishness of putting Him to a test. Sadly, many even today do not understand how foolish it is to put God to a test by seeking miraculous signs.
Help me today to seek you and not signs Lord.
