How does the Holy Spirit reveal God's truth in Hebrews?

In Hebrews 9:8, the Holy Spirit is described as signifying that the way into the holiest was not yet made manifest while the first tabernacle was still standing. This indicates that all the ceremonial laws and sacrifices were types pointing toward the ultimate fulfillment in Jesus Christ. His arrival and obedience clarified and revealed the truth of salvation that was previously obscured by the Old Covenant rituals. The Holy Spirit plays an active role in illuminating this truth, affirming that our understanding of God’s redemptive plan is only complete through Christ, who abolished the old way and brought forth a new covenant of grace.
