A King’s children are ordained to be Princesses and Princes even before they are conceived.
Not by virtue of their earning a title on their own, but by virtue of who their father is.
After they are born, and as they live out their lives, and as the world can see them standing beside the example of the King — it becomes clearly evident whether they are truly His or are illegitimate.
ELECTION

Even before he made the world, God loved us and chose us in Christ to be holy and without fault in his eyes. God decided in advance to adopt us into his own family by bringing us to himself through Jesus Christ. This is what he wanted to do, and it gave him great pleasure. So we praise God for the glorious grace he has poured out on us who belong to his dear Son. He is so rich in kindness and grace that he purchased our freedom with the blood of his Son and forgave our sins. He has showered his kindness on us, along with all wisdom and understanding. God has now revealed to us his mysterious will regarding Christ—which is to fulfill his own good plan.
Ephesians 1:4-9 NLT
BOASTING

But God is so rich in mercy, and he loved us so much, that even though we were dead because of our sins, he gave us life when he raised Christ from the dead. (It is only by God’s grace that you have been saved!) For he raised us from the dead along with Christ and seated us with him in the heavenly realms because we are united with Christ Jesus. So God can point to us in all future ages as examples of the incredible wealth of his grace and kindness toward us, as shown in all he has done for us who are united with Christ Jesus. God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Salvation is not a reward for the good things we have done, so none of us can boast about it. For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago.
Ephesians 2:4-10 NLT

And have you forgotten the encouraging words God spoke to you as his children? He said, “My child, don’t make light of the Lord ’s discipline, and don’t give up when he corrects you. For the Lord disciplines those he loves, and he punishes each one he accepts as his child.” As you endure this divine discipline, remember that God is treating you as his own children. Who ever heard of a child who is never disciplined by its father? If God doesn’t discipline you as he does all of his children, it means that you are illegitimate and are not really his children at all.
Hebrews 12:5-8 NLT
