When you have duel citizenship

“But as it is, they desire a better country, that is, a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared for them a city.” (Heb. 11:16 ESV)

Duel citizenship: being a citizen of two countries simultaneously and sharing the rights and responsibilities of the citizens in each country. 

We are citizens of God’s kingdom

“But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself.” (Phil. 3:20-21 ESV)

 “He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son,” (Col. 1:13 ESV)

While here, we represent Christ

“Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God.” (2 Cor. 5:20 ESV)

Therefore…

“Let not your hearts be troubled. Believe in God; believe also in me. In my Father's house are many rooms. If it were not so, would I have told you that I go to prepare a place for you? And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also.” (John 14:1-3 ESV)

“Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more. And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.” (Rev. 21:1-4 ESV)

Quote:

"I must keep alive in myself the desire for my true country, which I shall not find till after death; I must never let it get snowed under or turned aside; I must make it the main object of life to press on to that country and to help others to do the same." - C.S. Lewis
