Why is “Fully God and Fully Man” so important?

             The first Adam was created by God in perfection. However; Adam failed from the beginning and sin came to us and the land that brought us a heritage of sinful nature.

21 For since by man came death, by Man also came the resurrection of the dead. 22 For as in Adam all die, even so in Christ all shall be made alive. (1Cor 15:21-22)

17 For if by the one man’s offense death reigned through the one, much more those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.) (Roms 5:17,19)  Since sin was brought into the world by man then it should be removed by man.  If Christ came in spiritual form, then He could not shed His blood as sacrifice for us since all things are cleansed with blood, and without the shedding of blood there is no forgiveness. (Heb 9:22)  Just as Adam and Eve needed a living sacrifice with shedding of blood to cover their sin, we need it too.  Jesus came from God as our living sacrifice (the perfect one) and shed His blood to cover our sins. (Heb 10:4-7)

Christ came for our redemption and He will be the only mediator for us

      

       The tabernacle on earth in Old Testament is the shadow of the sanctuary in heaven.  In the old Testament time, the high priest came to the inner room (the Most Holy Place) once a year, and always with shed blood which is the offering for himself and for the sins the people committed.  When Christ came as the high priest, He enters the Most Holy Place with His own blood (Himself as a perfect sacrifice) to cover the sins for all people. As a result our sins are cleansed when we accept His and we escape eternal death.  In order to intercede for us before God, this high priest needs to have the same characters as God that we would associate to God: holy, blameless, pure, set apart from sinners, exalted above all heavens. ²⁶  Such a high priest truly meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. (Heb 7:26)  Christ is the mediator of the new covenant.  When Jesus Christ comes to the Father’s throne, he has to be fully God to face God and represent us as fully man.  “5 For there is one God and one Mediator between God and men, the Man Christ Jesus,” (1Tim 2:5).  Jesus became the only mediator for us between God and humanity.  As He is fully man, he can understand humanity in areas of suffering and weakness. ¹⁷  For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. ¹⁸  Because he himself suffered when he was tempted, he is able to help those who are being tempted. (Heb 2:17-18).  And as He is fully God in holiness, he can intercede for us.
