What connection has our war with this consummation [of the Millennium]? The progress of the promised grace has subdued its first enemy, idolatry. This destroyed man's allegiance to God. It must subdue the second enemy, which is man's hostility to man. This hostility assumes civic and social forms. It is monarchic, slavic, disuniting. Against these, march democracy, unity, fraternity, every man the equal and the brother of every man. To gain this victory we are now contending. . . . All governments based on the few, by the few, and for the few, are hostile to the government of Christ, and must be abolished before his Glory fully comes. [pp. 379-380]
The Union must be preserved, not alone because it was essential to our own welfare, but because through its preservation would the divine doctrine of popular government live among men. If America is lost, the world is lost. [p. 382]
God, my friends, not you, made man, of one father, that all might be brethren, that each should in honor prefer one another, esteeming others better than themselves. He is pushing us forward to His, not our, millennium. He is using and blessing us if we choose to work with Him. [p. 384]
