8 The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:
8 The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still functioning.
8 By this the Holy Spirit indicates that the way into the holy places is not yet opened as long as the first section is still standing
8 This was the Holy Spirit's way of showing with a visible parable that as long as the large tent stands, people can't just walk in on God.
8 the Holy Spirit indicating this, that the way into the Holiest of All was not yet made manifest while the first tabernacle was still standing.
8 By these regulations the Holy Spirit revealed that the entrance to the Most Holy Place was not freely open as long as the Tabernacle and the system it represented were still in use.
Matthew Henry's Commentary on Hebrews 9:8
Commentary on Hebrews 9:6-10
(Read Hebrews 9:6-10)
The apostle goes on to speak of the Old Testament services. Christ, having undertaken to be our High Priest, could not enter into heaven till he had shed his blood for us; and none of us can enter, either into God's gracious presence here, or his glorious presence hereafter, but by the blood of Jesus. Sins are errors, great errors, both in judgment and practice; and who can understand all his errors? They leave guilt upon the conscience, not to be washed away but by the blood of Christ. We must plead this blood on earth, while he is pleading it for us in heaven. A few believers, under the Divine teaching, saw something of the way of access to God, of communion with him, and of admission into heaven through the promised Redeemer, but the Israelites in general looked no further than the outward forms. These could not take away the defilement or dominion of sin. They could neither discharge the debts, nor resolve the doubts, of him who did the service. Gospel times are, and should be, times of reformation, of clearer light as to all things needful to be known, and of greater love, causing us to bear ill-will to none, but good-will to all. We have greater freedom, both of spirit and speech, in the gospel, and greater obligations to a more holy living.
