Contrast between the system and priesthood of Moses, and the ministry and priesthood of Christ, are Scripturally and rationally made. Jesus brings a better hope to draw near to God by a better covenant.
The writer takes his audience to a mysterious passage in Genesis that was preserved by God for this very moment and mission. To prepare them to accept a priesthood superior to the one given to them by Moses.
In a gentle tone he tells them that better things belong to our salvation. Nudging them forward, encouraging them not to be sluggish, since God is faithful, as Abraham realized. God’s reliability is an anchor of hope.
Having pointed out that their mixed feelings about Christ rendered them low interest Christians, he proceeds to warn them that this is a pathway to apostasy, a path from which there is little, if any, chance of recovery.
Having introduced Jesus as our Great High Priest, the writer now develops the difference between the sons of Aaron and the Son of God. He closes the chapter critical of Christians who refuse to grow in Christ.
