These will wage war against the Lamb, and the Lamb will overcome them, because He is Lord of lords and King of kings, and those who are with Him are the called and chosen and faithful. – Revelation 17:14

At this moment, my brethren and sisters, we, who follow the footsteps of King Jesus, are soldiers of an army which has invaded this world. This land belongs to our great Leader for He made it. It was right that everywhere, all round the globe, His name should be honored, for He is the King among the nations, and the governor thereof. But our race has revolted, set up another monarch, and bowed its strength to support another dynasty-the dynasty of darkness and death. Our race has broken the good and wholesome laws of the great Lord, the rightful King, and set up new laws and new customs altogether opposed to right and truth. This is the Great Rebellion, the Revolt of Manhood, the Sedition of Sinners. Now, no king will willingly lose his dominions, and therefore the great King of kings has sent His son to conquer this world by force of arms, though not by arms of steel, or weapons that cut and kill and wound, yet by arms more mighty far; and this earth is to be yet subdued to the kingdom of the Crown Prince, the Prince Imperial of heaven, Jesus Christ, the Lord. We, His regenerated people, form part of the army of occupation. We have invaded the land. Hard and stern hath been the battle up to this point. We have had to win every inch of ground by sheer push of pike. Effort after effort has been put forth by the Church of God under the guidance of her heavenly Leader, and none has been in vain. Hitherto the Lord hath helped us but there is much yet to be done. Canaanites and Hivites and Jebusites have to be driven out; yea, in fact, the whole world seems still to lie in darkness and under the dominion of the wicked one. We do but hold here and there a sacred fortress for truth and holiness in the land, but these we must retain till the Lord Jesus shall send us more prosperous times, and the battle shall be tamed against the foe, and the kingdom shall come unto our Prince…He who died once for all is now life’s source, center, and Lord. The living Christ is present among us as the commander-in-chief of the church militant. Let us refresh our souls by drawing, near to Him by the power of the Holy Ghost. ~ C.H. Spurgeon
