On June 16, 1858, as the newly nominated Republican candidate for the US Senate from Illinois, Abraham Lincoln delivered his famous “House Divided” speech, which highlighted the tensions between various factions in America regarding slavery. It caused a stir among Lincoln’s friends and foes. Lincoln felt it was important to use the “house divided” figure of speech which Jesus used in Matthew 12:25 because it was widely known and simply expressed. He used this metaphor “so it would strike home to the minds of men in order to rouse them to the peril of the times.”
If a divided house can’t stand, the opposite is true—an undivided house stands unified. In principle, that’s what the household of God is designed to be (Ephesians 2:19). Though made up of people from various backgrounds, together we’ve been reconciled to God (and each other) through Jesus’ death on the cross (vv. 14–16). In view of this truth (see Ephesians 3), Paul offers this instruction to believers in Jesus: “Make every effort to keep the unity of the Spirit through the bond of peace” (4:3). Today, when heightened tensions threaten to divide people who are otherwise united, such as our families and fellow believers, God can give the wisdom and strength needed to keep unity with one another through the help of the Spirit. This will cause us to be light in a dark, divided world.
