For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ,
He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love
When we accept Jesus as our Lord and Savior and are born-again, we become citizens of the Kingdom of God. We are no longer citizens of the world and we’re no longer governed by the world’s “fear of lack” based system. We are conveyed into the Kingdom of God and His love based system.
But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the heavenly places in Christ Jesus,
Even Jesus when praying for believers, highlighted our position of being in the world but not of the world.
I have given them Your word; and the world has hated them because they are not of the world, just as I am not of the world. I do not pray that You should take them out of the world, but that You should keep them from the evil one. They are not of the world, just as I am not of the world.
So what does all this mean? Are we to adopt a monastic lifestyle where we hide from everyone until we can “go home”? No! We are called to be ambassadors to a lost and dying world. An ambassador is not a citizen of the nation he is appointed to, instead he represents the King or President of his home country in a foreign land.
2 Corinthians 5:20
Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.
We are to help reconcile lost men and woman to God by telling them about His goodness and love. We are to do this while never forgetting where our eternal home is. When we realise that our home is not this world, we can see the world for what it is, a world that is passing away.
2 Corinthians 4:18
while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal.
Understanding that our citizenship is in the eternal, not the temporary, will help us to not be so easily ensnared by the temptations of this world.
1 John 2:15-17
Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world. And the world is passing away, and the lust of it; but he who does the will of God abides forever.
All this doesn’t mean that God wants us to go without while in this world, He knows that we need things to live. If we remained focused on Him and His Kingdom, then everything we need will be provided to us.
“Therefore I say to you, do not worry about your life, what you will eat or what you will drink; nor about your body, what you will put on. Is not life more than food and the body more than clothing? Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not of more value than they? Which of you by worrying can add one cubit to his stature? “So why do you worry about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin; and yet I say to you that even Solomon in all his glory was not arrayed like one of these. Now if God so clothes the grass of the field, which today is, and tomorrow is thrown into the oven, will He not much more clothe you, O you of little faith? “Therefore do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For after all these things the Gentiles seek. For your heavenly Father knows that you need all these things. But seek first the kingdom of God and His righteousness, and all these things shall be added to you. Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble.
Remember who you are, a son/daughter of the most high God and a citizen of Heaven right now!
