Sons, citizens and ambassadors

When we are born again, we are born into a kingdom, the kingdom of God. We are born as sons and daughters of the King of heaven and earth Himself! We are, by that birth, children, citizens and ambassadors.

My Father is King. I am my Father's son!

But when the fullness of the time had come, God sent forth his Son, born of a woman, born under the law, to redeem those who were under the law, that we might receive the adoption as sons. And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, "Abba, Father!" Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ. --Galatians 4:4-7 

For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. --Romans 8:29 

Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; as obedient children, not conforming yourselves to the former lusts, as in your ignorance; but as He who called you is holy, you also be holy in all your conduct, because it is written, "Be holy, for I am holy." --1 Peter 1:13-16

My Father is a King. I am a citizen of His Kingdom!

Jesus answered and said to him, "Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God." --John 3:3

Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, --Ephesians 2:19
