This means my “blood of the covenant,” which is to be poured out in behalf of many for forgiveness of sins. This is taken from Matthew 26:28.
God could apply the value of Jesus’ shed blood to Adam’s descendants. He could also adopt certain devoted humans “as sons” by anointing them with holy spirit. Romans 8:14-17 tells us: “For all who are led by God’s spirit are indeed God’s sons. For you did not receive a spirit of slavery causing fear again, but you received a spirit of adoption as sons, by which spirit we cry out: “Abba, Father!” The spirit itself bears witness with our spirit that we are God’s children. If, then, we are children, we are also heirs—heirs indeed of God, but joint heirs with Christ—provided we suffer together so that we may also be glorified together.”
Being considered to be without sin in God’s eyes, they would in a sense be like Jesus, the sinless Son of God. These anointed ones would become “joint heirs with Christ” and have the opportunity of becoming “a kingdom of priests.” (Exodus 19:6)
This was a privilege that the nation of Israel under the Law could have had. Concerning the “joint heirs with Christ,” the apostle Peter stated: “You are ‘a chosen race, a royal priesthood, a holy nation, a people for special possession, that you should declare abroad the excellencies’ of the One who called you.” (1 Peter 2:9)
How vital the new covenant is! It enables Jesus’ disciples to become the secondary part of Abraham’s offspring.
