Philippians 3:20-21

But (we are different, because) our citizenship is in heaven. And from there we eagerly await (the coming of) the Savior, the Lord Jesus Christ; who, by exerting that power which enables Him even to subject everything to Himself, will transform our earthly bodies so that they will be like His glorious resurrected body. 

Our citizenship as believers is in Heaven. Therefore, we should occupy this earth as representatives of God from Heaven, built up in faith and prepared for the coming of the Lord. As we recognize the signs of the times and keep our hearts pure toward God. We will see the coming of Jesus and our resurrected bodies.
