There is no doubt, for one moment, in the book of Revelation that the powers that array themselves against Christ will succeed. They will try. They will use all the earthly power at their disposal to rebel against God and persecute His people. And they will fail because Jesus Christ is Lord of lords and King of kings. No one can thwart His plans or disobey His authority successfully. Jesus is in control.
And those with Him are uniquely His. They are called by Him. They have responded to that call. And in that response they realize that all along they were chosen in Him: the people of God by His design and purpose. And they are faithful to Him. They obey and submit to the King of kings and Lord of lords and find themselves on the victory side of the war against the Lamb.
So these very simple descriptions have profound meaning. I see Jesus for Who He is and I realize that nothing in this present world will destroy Him or His work. I see who I am as one of His faithful called and chosen ones. And I know that serving Him and obeying His command in the fray will be rewarded with sure victory over those who would rebel against God.
