Jesus ministry at the right hand of the Father is one of the rarest features of the Pauline Revelation. The problem of the authorship of Hebrew is settled. Hebrews is a part of that Revelation. No one else could have given it as Paul has given it to us. It is a Revelation of what Jesus did from the time He was made sin on the cross, until He sat down on the right hand of the Father.
That entire work is given to us in this wonderful unveiling. Not only did he make us know what Christ did for us in His Substitution, but he has made us know what the Holy Spirit, through the Word on the ground of the Substitutionary work of Christ does in the individual life.
There are really four phases of this Revelation. First, what Christ did for us. Second, what the Holy Spirit, through the Word, done in us. Third, what Jesus is doing now at the right hand of the Father for us.
Fourth, what His love does through us in ministry. We spend must time studying what Christ has done for us , but very little has been given to what He does in us, and less has been given to what He is now doing in His Great High priestly office at the right hand of the Father. His entire ministries for us would have been a total failure had He not carried ministry now at the right hand of the Father on our behalf.
Jesus died as the Lamb. He arose as the Lord High Priest. His first ministry, after He arose from the dead, is illustrated in Jn. 20:15-18. Jesus met Mary after His Resurrection. She fell down at His feet, and no wonder. He said to her, Touch me not; for l am not yet ascended unto the Father: but go unto my brethren, and say to them, I ascend unto my Father and your Father, and your Father, and my God and your God. What did He mean? He died as the Substitute Lamb. He arose as the Lord High Priest.
Heb. 2:17, wherefore it behoved him in all things to be made like unto his brethren, that he might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people. He is a merciful and faithful high priest, not in things pertaining to man, but in things pertaining to God.
