Jesus Christ said in Mark 3:25: “And if a house be divided against itself, that house cannot stand.” President Lincoln quoted these words in our nation’s darkest hour, and it would be good for us to heed them again today. The anniversary of Gettysburg is a reminder of what it takes to recapture national unity once it is lost. A failure to learn this lesson will mean that this “government of the people, by the people, for the people, shall … perish from the Earth.”
