"In Him (Christ) 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). Scripture is clear, upon believing the gospel of Christ, you were sealed with the Holy Spirit of promise.
In Bible days, important letters were written on scrolls of parchment. It was rolled together and sealed in such a way that the recipient of the letter knew that no one had changed the message. We could say, it was signed, sealed and delivered. This custom was used to illustrate our security in Christ. Believers are sealed by God's Spirit.
The Holy Spirit of promise comes to you through faith in Jesus Christ (Galatians 3:2, 5). The Holy Spirit is the covenant promise of God to you and every believer (Acts 2:38-39). God says, "I will put My Spirit within you and cause you to walk in My statutes, and you will keep My judgments and do them" (Ezekiel 36:27).
The Holy Spirit is your seal of promise, to be your Guide, Counselor, Helper and Comforter. The Holy Spirit was promised to you as a believer in the Lord Jesus Christ (Ephesians 1:13). Every believer is sealed with the promise of the Spirit, unto the day of redemption (Ephesians 4:30). That's the day Christ returns and believers are glorified into His likeness (1 John 3:2).
