In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise. Ephesians 1:13
You were sealed with the Holy Spirit of promise. It’s not “sealed” like the marine mammal you see in circuses honking bicycle horns. And it’s not “sealed” like being trapped inside the mummy’s tomb forever … but that one is getting closer. So what is Paul getting at when he says we have been sealed? I think there are at least four things included in it.
Authenticity – Back in the days when software came on disks or CDs it often came with a certificate with a seal of authenticity to let you know you had the genuine item, that it wasn’t a pirated copy. You could be confident that it as going to function as expected and that it had all the features you wanted.
The Holy Spirit ensures and attests that our salvation is the real deal and it rests in no one but the One True God accomplished by His Anointed. No fakes, no substitutes, no sub-contractors.
Security – If you have ever been drug-tested for work or had bloodwork, you may have noticed the technician or nurse putting a bunch of stickers on the sample containers or bags. Those are there to prove the samples have not been tampered with. They affirm the integrity of the sample so the results of the tests can be trusted.
The Holy Spirit seals us so that our salvation cannot be tampered with. Because of that we know the results, like joy and peace and growth and answered prayers and so on can be trusted. Not only that, we can be confident that the end result of our salvation, our ultimate glorification in Christ’s presence is a sure thing.
Ownership – Cattlemen used to brand their herds so that even in a big group, it was easy for anyone to see which cows belonged to whom. Even now we mark our lunches, and our coffee cups and kids’ jackets so that ownership is clear.
The Holy Spirit seals us so we never have to question who we belong to. Not only that, but it should be easy for anyone else to tell it as well.
Authority – Your high school or college diploma. Your driver’s license. Your building permit. All of them have some sort of seal affixed to them indicating that some governing entity with the requisite authority has conferred on you some right or privilege or standing.
The Holy Spirit gives us the standing as children of God, joint heirs with Christ and further grants us the status as ambassadors for His kingdom.
You probably already knew it, but just for the record that’s an unbreakable seal.
