Mark 3:23-27

Satan would like nothing better than to divide us, as followers of Christ, collectively and personally. If he can get us to doubt each other or our own Christianity he wins and the world loses another voice for God......

If Satan can get us to concentrate on mans inherent failures and hypocrisies  instead of the ability of the Holy Spirit to change anyone who accepts salvation precept upon precept into the image of His Son..... then we perpetuate the works of evil and hinder the works of God. Christ within, the hope of glory, what we cannot do, He can!

Jesus’ reply in parables was actually a threefold message that contrasted unity and disunity. Nothing—including Satan’s kingdom—can stand if it is divided.
Whoever defeats Satan must be stronger than he. Jesus implies that He Himself has come to enter the house of the strong man, Satan, to seize his goods.

Mark 3:23-27

²³ So He called them to Himself and said to them in parables:  “How can Satan cast out Satan? ²⁴ If a kingdom is divided against itself, that kingdom cannot stand. ²⁵ And if a house is divided against itself, that house cannot stand. ²⁶ And if Satan has risen up against himself, and is divided, he cannot stand, but has an end. ²⁷ No one can enter a strong man’s house and plunder his goods, unless he first binds the strong man. And then he will plunder his house.
