In many ways Christians are like the soldiers of WWII who were in Europe when Germany surrendered and yet had to remain several months longer for the purpose of establishing the peace. For Christians, the battle has been decided – decisively, and our mission is to now preach the peace that has resulted. We should not go about our mission discouraged and dejected as if defeated, but joyously because of the knowledge of Christ’s victory over the world, sin and Satan. Yes, there are still pockets of resistance and there is much work to be done before we go home, but our attitude is constantly one of great joy, immense gratitude and unceasing praise knowing that the victory is sure in Christ.
I do not cease to give thanks for you, remembering you in my prayers, that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and of revelation in the knowledge of him, having the eyes of your hearts enlightened, that you may know what is the hope to which he has called you, what are the riches of his glorious inheritance in the saints, and what is the immeasurable greatness of his power toward us who believe, according to the working of his great might that he worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places, far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come. And he put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all in all.
(Eph 1:16-23)
