Answer: The Epistle to the Hebrews is occupied with Christ in contrast to Judaism, and we have Christ and His work unfolded to us. The rest is seen as but shadows which were the beginning of the doctrine or teaching, from which we must go on to what belongs to full growth.
The things mentioned in verses 1-2 are as far as Judaism could give them. Verses 4-5 are things belonging to Christianity.
It would be to profit if we could follow this out through the chapters and in reading the epistle, it is well to keep this in view.
Prophets and angels. Moses. Joshua and David; the Aaronic priest must all give way to Christ. He was to be a Priest forever after the order of Melchisedec. An earthly altar to give place to a Spiritual one. So the place of worship is within the veil. The many sacrifices that could never put away sins, pass away, and give place to the one great sacrifice that put away sin so perfectly, that every believer stands before God in its perfection (Heb. 10:4,12,14,174For it is not possible that the blood of bulls and of goats should take away sins. (Hebrews 10:4)
12But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; (Hebrews 10:12)
14For by one offering he hath perfected for ever them that are sanctified. (Hebrews 10:14)
17And their sins and iniquities will I remember no more. (Hebrews 10:17)). It could not be repeated.
The Son of God has accomplished it all, and is now a man living and glorified in God’s presence.
To go on unto perfection, is to learn everything in the light of Himself as God, and man, and to know that He is the one in whom we are accepted. There is no thought of what is commonly spoken of as sinless perfection, till Christ comes and claims His church; then we shall be in all His perfection: spirit, soul and body.
