Hebrews 10:15 says that the Holy Spirit himself bears witness to believers about what God has done, so the promise of forgiveness rests on God’s own testimony rather than on human effort. The verse is the author’s way of saying that the Spirit confirms the new covenant in Scripture. The writer of Hebrews, traditionally thought to be Paul or one of his close associates though the author is not named, is speaking to a Jewish-Christian audience who knew the old sacrificial system well.

What Hebrews 10:15 Means
The phrase “the Holy Spirit also testifies to us” means that the Spirit makes the truth of God’s promise known and sure to those who belong to Christ. In the flow of the passage, the writer has just said that Christ offered one sacrifice for sins forever. The Spirit then confirms that message by pointing back to words from the Old Testament prophet Jeremiah, which the author quotes as “after saying.” The verb “testifies” carries the idea of a witness giving reliable evidence in a courtroom.
The verse does not describe a feeling or a private revelation that anyone can invent. It points to the written Word, which the Spirit uses to assure God’s people that the new covenant is real and that its benefits are theirs. It does not promise that believers will always feel certain, and it does not say how the Spirit will speak in every individual life. What it does promise is that the testimony of God about his covenant is trustworthy and comes from God himself.
The Context of Hebrews 10:15
The letter to the Hebrews argues that Jesus is better than the priests, the sacrifices, and the covenant of Moses. Its readers were tempted to think that returning to the familiar rituals of the temple would give them more security. The author keeps returning to the finished work of Christ, who offered himself once and then sat down at God’s right hand. Verse 15 sits in the middle of that argument, and it links the completed sacrifice to the promise of a new covenant written on the heart.
Read in context, verses 12 through 18 form a single unit. The sacrifice is finished (verse 14), the Spirit confirms the covenant (verse 15), and the result is that God remembers sins no more (verse 17). Because of this, the writer concludes that there is no further offering for sin (verse 18). Seeing this flow changes the verse from a general statement about the Spirit into a specific point about why no other sacrifice is needed.

This is the prophetic promise that Hebrews 10:16 quotes in full. Reading it in its original setting shows the hope of a covenant written on the heart, which is the heart of the Spirit’s testimony in Hebrews 10:15. It helps the reader see that the new covenant was announced long before Christ came.
Romans 8:16
The Spirit himself testifies with our spirit that we are children of God…
(WEB)
Paul writes here that the Spirit testifies with our spirit that we are God’s children. The same idea of the Spirit’s inward witness appears in both passages. Romans 8:16 shows how that witness becomes a personal assurance for the believer.
A Short Prayer From Hebrews 10:15
Lord, thank you that your Spirit speaks truth to my heart and does not leave me to guess about your forgiveness. Help me to rest in the testimony you have given in Scripture, especially the promise that you remember my sins no more. When doubt rises, remind me that Christ has finished the work and that you have confirmed it. Teach me to trust your word more than my changing feelings. Amen.
