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. (Mark 3:24–26, NKJV)
The enemies of Jesus charged Him with casting out demons by the power of Satan (Mark 3:22-23). Jesus exposes their error by noting a fundamental principle: Chaos occurs where division exists. If their charge was true, then Satan was fighting against Satan. Division produces chaos, not calm. This principle is noteworthy incentive for us to pursue peace (Hebrews 12:14). A country at war with itself cannot long sustain the chaos of internal conflict. A divided family cannot long endure factious emotions and splintered loyalties. Christ will not indefinitely recognize and identify Himself with a church that is divided in doctrine and practice (Rev. 2:4-5). It is very wrong to think God is pleased with religious division by saying such things, as “join the church of your choice.” The chaos of doctrinal division renders this recommendation inept (not to mention unscriptural, John 17:20-21; 1 Corinthians 1:10; Ephesians 4:3). God’s kingdom is united in truth. Strong families stand on the solid rock of faith. And, God’s house stands on and upholds the truth of God (1 Timothy 3:15). Division is the work of Satan. Unity in truth is the work of God in Christ Jesus.
