In Him, you also, after listening to the message of truth, the gospel of your salvation— having also believed, you were sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance, with a view to the redemption of God’s own possession, to the praise of His glory.
Ephesians 1:13-14
Occasionally I have been foolish enough to venture into computers I have owned. After I figure out how to remove the external case, typically losing a few of the tiny screws that hold it on in the process, I sometimes find a component I cannot identify, but that I feel quite certain must be removed to remedy whatever problem exists with the device. Strapped to that component is normally a brightly colored sticker that says something about invalidating a warranty if it is removed. I hesitate, then break the seal.
Seals are important. They guarantee things. In the above example, they are designed to guarantee that I don’t mess with something I’ve got no business getting into. On educational transcripts, seals guarantee authenticity. On perishable foods, they guarantee freshness.
In Scripture we discover that God the Holy Spirit has a guaranteeing ministry, of sorts. It is known as His sealing ministry. Specifically, it guarantees two things. To understand these two things, we have to consult the Scriptures to understand how the sealing ministry is used in them.
The first way we see seals being used in the Bible is as a guarantee of ownership or identity. To illustrate the way the Bible references seals being used in this way, we can go to Genesis 41:42. There, Pharaoh gives Joseph his signet ring. A signet ring is a ring used to make impressions or seals in a soft material. Joseph was able to put Pharaoh’s identifying mark of ownership on whatever he wanted. Another place we see a seal being used as a guarantee of ownership is in Revelation 7:2-8. There, 144,000 are identified as God’s servants by a seal. They will be certainly identified as the servants of the one true God by the fact that they have His seal upon them. Much as cattle brands today identify the owners of animals, in biblical times a seal identified who owned the thing or person which bore the seal.
The second way in which a seal was used in Scripture was to show security. The colorful story of Daniel in the lion’s den is an example of this use. Daniel 6:17 says that Darius sealed the stone over the den in order to guarantee that Daniel was securely inside. In a similar New Testament use of a seal, we can go to Matthew 27:66. There, the Pharisees and the chief priests put a seal on Christ’s tomb. Again, the seal upon the tomb demonstrated security. No one would open Jesus’ tomb without breaking the seal. His body was secure (or so they thought).
The significance of the Holy Spirit’s sealing ministry is visible in these literal uses of seals in the Bible. The Spirit’s indwelling presence in the believer in Jesus Christ guarantees his or her identity. God identifies the believer as one of His own. Our recognition of our unique identity as God’s own possession informs every aspect of how we live.
There is a poignant moment in the movie Toy Story, when the main character, a cloth doll named Woody, forgets what he’s all about. Then, he looks at the bottom of his boot and spies the name of his owner, Andy, carved into the plastic. As a result, Woody regains his sense of who he is and what he should be about. As believers in Christ, we, too, need to check our metaphorical boots from time to time to remind ourselves of whose we are. Being sealed as God’s own is a powerful incentive for holy living because it says that we are not our own, that we are to be living for Another.
Besides guaranteeing the believer’s identity, the sealing of the Spirit in the life of the believer is a guarantee of the believer’s security. This guarantee of security is particularly apparent in today’s verse. Paul speaks of the Holy Spirit in Ephesians 1:14 as “a pledge of our inheritance.” The meaning of the word for “pledge” literally is the “payment of part of a purchase price in advance.” The point is that the Spirit being given to believers is the first installment, the down payment, in our redemption. Our redemption will culminate in the redemption of our bodies, or our glorification (Romans 8:23). We live in anticipation and expectation of this future reality. While our glorification is yet future, it’s as good as done. God has already made the down payment. We already have His seal, the Holy Spirit, so we can live in confidence that we will spend eternity glorified in the presence of the glorious Christ.
Today, in response to what we’ve seen about the sealing ministry of the Holy Spirit, we’ve got an opportunity to thank God that we are His. What’s more, we can express gratitude to Him that we will certainly appear with His Son in glory. We have His seal on it.
