In the Old Testament, we are told that behind the “veil” is the Holy of Holies, where only the High Priest is allowed to enter.
In the New Testament, “the veil of the temple was rent” (Mk. 15:38), which means it was divided or split, after the crucifixion of Jesus. Jesus is now our High Priest. If you remember during the transfiguration in which Peter, James, and John were present, we were told to no longer look to Moses or Elijah, but instead to “hear Him,” which was Jesus, our new High Priest, our advocate or mediator to the Father. This is what happened when the veil was rent, Jesus was made Holiest of all flesh, those who lived upon the earth. A complete sacrifice so no longer were animal sacrifices to be made (Hebrews 9). He was the Son of God before, but now He is also the Son of Man, crucified for our sakes. The first covenant was imperfect, incomplete. It is only in Jesus, that all is made whole and complete. He is the end of our salvation, where no longer is another needed.
To whom is this promise for? To those who are willing to crucify the self-life and enter in behind the veil which is Jesus’ flesh. To take on His death is to enter into covenant with Him. The two are inseparable…No death…No covenant. It is the “children of promise” that are “counted for the seed”, “not the children of the flesh.” (Romans 9:8)
Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: Romans 6:3-5 (Also 2 Cor. 4:10-12)
This is how we can enter into the Holy of Holies, where true fellowship with our Father is kept and preserved by the One who was crucified for our sakes. It is “through the veil, that is to say, his flesh.” (Heb 10:20)
“Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. For sin shall not have dominion over you: for ye are not under the law, but under grace.” (Romans 6:13,14)
It is here, behind the veil, behind His crucified flesh, in which we can “hide” in which we can now not be ashamed, in the shadow of His wings, which bring us unto eternal life.
However, if you have faith show it out of your works, because without works, faith is dead being alone. (James 2:17,18)
