IN CHRIST Rom.8:1
"There is, therefore, now no condemnation to them who are in Christ Jesus, who walk not after the flesh, but after the Spirit".
You don’t need to be very bright not to notice, that when reading the New Testament there is this recurring phrase "in Christ", "in Christ Jesus" e.g. 2 Cor.5:17 most of you know: "He that is In Christ is a new creation" Eph.1:3 "Blessed us with all spiritual blessings in heavenly places In Christ, v.7 In Whom ( In Christ) we have redemption through his blood, the forgiveness of sin...."
To be "In Christ" means to be no longer "In Adam" for Christ is the "Last Adam" 1Cor.15:45, and 1Cor.15:22 tells us "that In Adam all die, even so In Christ shall all be made alive."
Every unbeliever is still In Adam, a member of the fallen race, and because he is a fallen creature he is under condemnation, John 3:17, "He that believeth not, is condemned already". Therefore, he mast be "born again", and the moment a man is born again he is no longer In Adam but In Christ a new creation.
Now in the picture gallery of the Old Testament, there is the parallel. When Aaron, the high priest, entered into the tabernacle, the Holiest of Holies, he wore on his chest what is described in the book of Exodus as the breast plate. The breast plate had 12 big precious stones on it, and on the stones it had the names of the twelve tribes of Israel engraved, and when Aaron presented himself before God, all the children of Israel appeared with him.
So it is with our Saviour, for we read in Hebrews 9:24 "For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us". Of course in our case, the names are not written on precious stones but engraved on His hands and feet.
In future when you see the phrase "In Christ" remember that every true child of God has been Coll.2:12, "buried with Him in baptism, wherein also ye are risen with Him through the faith of the operation of God".
