According to the work and ministry of Christ, this book has a turn at this verse, a turn from earth to heaven. To the end of ch. 6, what is revealed is mainly Christ's work on earth, typified by the priesthood of Aaron. That section is the word of foundation. From this verse, Christ's ministry in heaven according to the order of Melchisedec is unveiled. This section is the word of perfection, which shows us how the heavenly Christ ministers in the heavenly tabernacle. His purifying of sins is typified by the work of Aaron, while His sitting down on the right hand of the Majesty on high (Heb. 1:3) is according to the order of Melchisedec (Psa. 110:1, 4). His work on the cross on earth, typified by the work of Aaron, affords us forgiveness of sins. His ministry on the throne in heaven ministers to us the overcoming of sin. His cross delivered us out of Egypt; His throne brings us into Canaan. The Hebrew believers participated in His work on the cross. Now they had to press on to enter into the enjoyment of His ministry on the throne.
