Hebrews 8:1

Hebrews 8:1 says, Now of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens;  In this verse and verse two, the writer summarizes what he had been saying about Jesus Christ.  We have the only high Priest that we will ever need.  The earthly high priests had to enter the inner part of the sanctuary behind the veil to offer sacrifices, but Jesus tore that veil away.  We cannot confine Christ to a particular place where we must go to speak to Him. Through the holy Spirit, we are always in the presence of God, no matter what we are doing.  Christ is sitting on the right hand of the Father.  Again, I am not sure we will ever understand the Trinity in this lifetime, but we can understand that Jesus Christ died for us and makes intercession for us with the Father.  

Verse two adds, A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.  Christ is the minister of the sanctuary and the true tabernacle.  This is not a physical place made by man, but a spiritual place made by God.  The old tabernacle was made under the law, but the new tabernacle was made under the grace of God.  

Verse three continues, For every high priest is ordained to offer gifts and sacrifices: wherefore it is of necessity that this man have somewhat also to offer.  The high priest presented the sacrifices of the people to God.  The people brought the sacrifices to him, and he offered them to God.  If Christ is to be our high Priest, then He must offer a sacrifice, which He does.  Christ offers Himself, the only perfect sacrifice, to God in our place.  

Verse four states, For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:   Christ is not a priest by earthly standards, having not be born into the priestly tribe, but He is the high Priest by heavenly calling.  There were still priests that offered sacrifices under the law of God, and there still are some today, but no one can be saved by the law.  

Verse five adds, Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.  Earthly priests serve under the shadow of heavenly things.  Christ serves as our high Priest, already knowing about all there is to know about heaven and the earth.  When we become followers of Christ, we have the assurance that one day we will understand all there is to know about heaven, since Christ said that He went to prepare a place for us.
