In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise [Eph. 1:13].
This section, I believe, is one of the most wonderful in Scripture. “Well,” somebody says, “he doesn’t mention regeneration here.” Actually he does, and in a marvelous way, because now we’re passing from God’s work for us to the work of the Holy Spirit in us. The work of God in planning the church and the work of the Lord Jesus in redeeming the church and paying for it were objective. The work of the Holy Spirit in protecting the church is different because it is subjective; it is in us.
In this work of regeneration and renewing, the Holy Spirit causes a sinner to hear and believe in his heart, and that makes him a child of God. The Lord Jesus said, “… Ye must be born again” (John 3:7). How are we to be born again? John explains, “But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name” (John 1:12). We need simply to believe on His name.
“In whom ye also trusted, after that ye heard the word of truth” Hearing means to hear not just the sound of words but to hear with understanding. Paul wrote, “But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; but unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God” (1 Cor. 1:23–24). Who are the called? Are they the ones who just heard the sound of words? No, it means those who heard with understanding. God called them. It was not just a call of hearing words, but a call where the Holy Spirit made those words real. Faith comes by hearing, and hearing by the Word of God, according to Romans 10:17. Those who are called hear the Word of God and they respond to it. Then what happens? Peter puts it this way: “Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever” (1 Pet. 1:23). The Word of God goes out as it is going out even through this printed page. We are saying that the Son of God died for you and if you trust Him, you will be saved. “Well,” someone may say, “I read these words, but they mean nothing to me.” Someone else, however, will read or hear this message, and the Spirit of God will apply it to his heart so that he believes—he trusts—and the moment he trusts in Christ, he is regenerated. Believing is the logical step after hearing. It may not be the next chronological step, but it is the logical step. “In whom ye also trusted, after that ye heard the word of truth.” This is the best explanation of what it means to be born again that I know of in the Word of God. You hear the word of truth—the gospel of your salvation, the good news of your deliverance—and you put your trust in Christ.
“In whom also after that ye believed, ye were sealed with that holy Spirit of promise.” I would like to remove the word after from this verse because these are not time clauses. They are what is known in the Greek as genitive absolutes, and they are all the same tense as the main verb. It means that when you heard and you believed, you were also sealed: it all took place at the same time. A truer translation would be, “In whom also you, upon hearing [aorist tense] the word of truth, the good news of your salvation, in whom also on believing [aorist tense] you were sealed with the Holy Spirit of promise.” This is, by the way, when the baptism of the Holy Spirit occurs. You are baptized the moment that you trust Christ. You are also sealed the moment that you trust Christ. The Holy Spirit first opens the ear to hear, and then He implants faith. His next logical step, you see, is to seal the believer.
There are people today who argue whether God the Father or God the Son seals with the Holy Spirit, or whether the Holy Spirit Himself does the sealing. That type of argument wearies me. They tried to split hairs in that way in the Middle Ages and would argue how many angels could dance on the point of a needle. You toss that around for a little while, and it will get you nowhere. I understand this verse to mean that the Holy Spirit is the seal. God the Father gave the Son to die on the cross, but the Son offered up Himself willingly. So both the Father and the Son gave. God the Father and God the Son both sent the Holy Spirit to perform a definite work, but it is the Spirit who does the work. He regenerates the sinner and He seals the sinner at the same time, and I think that the Spirit Himself is that seal.
There is a twofold purpose in the sealing work of the Holy Spirit. He implants the image of God upon the heart to give reality to the believer. You know that a seal is put down on a document and that seal has an image on it. I think that is exactly what the Spirit of God does to the believer. “He that hath received his testimony hath set to his seal that God is true” (John 3:33). Apparently, this is the thought here—God has put His implant upon the believer.
The second purpose of the sealing is to denote rightful ownership. “Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity” (2 Tim. 2:19). The fact that He makes you secure does not mean that you can live in sin. If you name the name of Christ, you are going to depart from iniquity. If there is not this evidence, then you were not regenerated or sealed.
The Holy Spirit is the seal, and that guarantees that God is going to deliver us. We are sealed until the day of redemption. The day will come when the Holy Spirit will deliver us to Christ. It’s nice to be sealed like that—we are just like a letter that is insured. In the old days they would put a seal on it. Today they just stamp it with a special stamp, but it still means that the post office guarantees to deliver that letter...
