I heard a preacher recently say that for God's Word to manifest itself in your lives you need both the Word and the Spirit to be successful. The book of John starts out by saying, "In the beginning was the Word and the Word was with God and the Word was God. He was with God in the beginning." Now we understand the Word to be Jesus and we see this all through out the scriptures that Jesus is called the Word and that the Word was flesh - it was God living and interacting in the physical realm.
It is not surprising that Paul starts out the book of Romans telling us that Jesus was a descendant of David, and we have recently discussed the importance of this truth. But since we understand our Lord Jesus to be both physical in body and spiritual in mind and Spirit it is of the utmost importance to understand that Jesus' resurrection from the dead by the Spirit of holiness to be the pinnacle of history and the absolute proof that Jesus was who he claimed to be - The Son of God.
Going back to our account in the book of John, we see some important truths starting in vs. 10, "He was in the world and though the world was made through him the world did not recognize him. He came to that which was his own but his own did not receive him. Yet to all who receive him to those who believe in his name, he gave the right to become children of God. Children born not of natural descent nor human decision or a husband's will, but born of God. The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only who came from the father full of grace and truth." ( John 1:10-14 )
So we have the Word, who was God and who is God and who created all things and who came in human form to break the curse of the law and to redeem that which the kingdom of darkness acquired during the fall of man... and he was in human form.
Now our Jesus was crucified and lay in the grave and at that point the penalty of sin had been paid for - Jesus shed his blood to atoned for the sins of the entire world once for all, past present and future. Hebrews talks about this in chapter 7, verse 27, "Unlike the other high priest, he (Jesus) does not need to offer sacrifices day after day, first for his own sins and then for the sins of the people. He sacrifices for their sins once for all when he offered himself." This is imperative to understand that Jesus paid the penalty for sin once for all - But it is only through his resurrection from the dead that he took the position of High Priest before God and entered into the heavenly tabernacle to present His blood on the mercy seat. Starting in verse 28 of Hebrews 7, it goes on to talk about this when it says, "For the law appoints as high priest men who are weak. But the oath which came after the law appointed the Son who has been made perfect forever. The point of what we are saying is this: We do have such a High Priest, who sat down at the right hand of the throne of the Majesty in heaven and who serves in the sanctuary; the true tabernacle set up by the Lord, not by man" ( Hebrews 7:27 - Hebrews 8:2 ) this is why it is both the death of Jesus and the resurrection of Jesus that gives us assurance of Faith.
Now Paul is stressing this point in the beginning of Romans, when he said, it was through the Spirit of Holiness that Jesus was raised from the dead and this demonstration of power is the proof that he was the Son of God! It goes back to what that preacher said, you need both the Word and the Spirit to manifest the truth that is God's Word. The Word was prophesied and spoken over thousands of years until that which was spoken came to pass by the movement of the Spirit and to the obedience of those the Word was spoken to, thus fulfilling the Word. The Word fulfilled itself by the demonstration of Power by the Holy Spirit in that and of the person of Jesus Christ who is the Son of God both in the physical and in the spiritual realm.
