Many of the prominent teachings of Scripture are presented in very short phrases, often just a couple of words.  A major doctrine for the Church Age is found in two words – “in Christ.”  This phrase is only revealed in the epistles and therefore identified as one of the mystery doctrines concerning Christ and His Church.  It is not a mysterious teaching; just one that was not previously revealed in the Old Testament and is specific to the formation of the Church on the day of Pentecost.   This is not to say that prior to the formation of the Church that believers were not in the family of God; they were.  However, with the beginning of the Church there are certain privileges for Christians because Christ has been exalted above every name.  Perhaps the most important prayer found in Scripture is recorded for us in John 17.  It is the night of Jesus’ betrayal and He is praying to the Father.  "And now, glorify Thou Me together with Thyself, Father, with the glory which I had with Thee before the world was” (John 17:5). He has the assurance that the Father will grant His petition; but the Father abundantly answers.  “Now to Him who is able to do exceeding abundantly beyond all that we ask or think(Eph 3:20).  The Apostle Paul gives us the answer to that prayer… “Therefore also God highly exalted Him, and bestowed on Him the name which is above every name, that at the name of Jesus every knee should bow, of those who are in heaven, and on earth, and under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father” (Phil 2:9-11).  Furthermore, the writer of Hebrews adds … “Sit at My right hand, until I make Thine enemies a footstool for Thy feet" (Heb 1:13).  The apostles, primarily Paul, would be responsible for teaching previously unrevealed Truth related to the believers new identity in Christ. Thus, he authenticates his message to the Christians in Ephesians with these words … “For this reason I, Paul, the prisoner of Christ Jesus for the sake of you Gentiles — if indeed you have heard of the stewardship of God's grace which was given to me for you; that by revelation there was made known to me the mystery, as I wrote before in brief.   And by referring to this, when you read you can understand my insight into the mystery of Christ, which in other generations was not made known to the sons of men, as it has now been revealed to His holy apostles and prophets in the Spirit; to be specific, that the Gentiles are fellow heirs and fellow members of the body, and fellow partakers of the promise in Christ Jesus through the gospel, of which I was made a minister, according to the gift of God's grace which was given to me according to the working of His power” (Eph 3:1-7).  Therefore, in teaching the mystery doctrines of Christ, Paul referred to the believer’s identification with Christ nearly two hundred times.  To the Galatians he wrote …”For you are all sons of God through faith in Christ Jesus” (Gal 3:26).  Furthermore, there is true equality in relationship with Christ … “There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus” (Gal 3:28).  The key in these truths is “being in Him, in Christ.”  Note that the means of being identified with Christ is through faith in Christ Jesus.  His finished work on the Cross in paying the sin debt of humanity and His resurrection are proof that the Father was satisfied with the Work of the Cross.  Redemption was and is completed, available to all.  Simple faith in those facts places anyone “in Christ.”  It is this identification or position of being in Him why Paul writes … “Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ” (Eph 1:3).   What a phenomenal truth.  All that is needed in the life for the Christian to glorify Christ during his earthly journey has been provided.  The Apostle Peter stated the same truth with these words … “His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness” (2 Pet 1:3).  That is total provision for every believer merely waiting to be claimed by faith as we learn and allow His Word to function in our lives.
