All this talk of patriotism and citizenship that goes on in the secular world. There is only ONE citizenship with which we Christians should concern ourselves, and that is the following one that is mentioned by the Apostle Paul in his Epistle to the brethren at Ephesus:
Keep in mind that Paul was a citizen of Rome, which was the most powerful empire in the world in its day; and yet, similar to Moses, he was willing to forsake it all, in order to seek the greater rewards of God's Kingdom.
Concerning Moses, we are told in Hebrews:
"By faith Moses, when he was born, was hid three months of his parents, because they saw he was a proper child; and they were not afraid of the king’s commandment. By faith Moses, when he was come to years, refused to be called the son of Pharaoh’s daughter; Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season; Esteeming the reproach of Christ greater riches than the treasures in Egypt: for he had respect unto the recompence of the reward. By faith he forsook Egypt, not fearing the wrath of the king: for he endured, as seeing him who is invisible."
Hebrews 11:23-27, KJV
Exactly how did Paul view his former life as a Law-bound Pharisee? Consider this:
"Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,"
Philippians 3:8, KJV
"These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth. For they that say such things declare plainly that they seek a country. And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city."
Hebrews 11:13-16, KJV
Finally, please remember this:
"Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever."
1 John 2:15-17, KJV
