A further application of the principle of applying the lamb’s blood at Passover is found in the Book of Deuteronomy.
Therefore shall ye lay up these my words in your heart and in your soul, and bind them for a sign upon your hand, that they may be as frontlets between your eyes. And ye shall teach them your children, speaking of them when thou sittest in thine house, and when thou walkest by the way, when thou liest down, and when thou risest up. And thou shalt write them upon the door posts of thine house, and upon thy gates: That your days may be multiplied, and the days of your children, in the land which the LORD sware unto your fathers to give them, as the days of heaven upon the earth. For if ye shall diligently keep all these commandments which I command you, to do them, to love the LORD your God, to walk in all his ways, and to cleave unto him. (Deuteronomy 11:18-22 KJV)
Notice that God commanded his people to write his words upon the door posts of their house, door posts which would have been smeared with the Passover lamb’s blood. John tells us that Jesus himself is the Word of God who was made flesh and dwelt among us. Paul calls Jesus our Passover, so of course, the lamb’s blood represents Jesus’ blood. Now recall Jesus’ testimony when he revealed that he was the bread of life. He said in part,
“Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day. 55 For my flesh is true food, and my blood is true drink. 56 Whoever feeds on my flesh and drinks my blood abides in me, and I in him. 57 As the living Father sent me, and I live because of the Father, so whoever feeds on me, he also will live because of me. 58 This is the bread that came down from heaven, not like the bread the fathers ate, and died. Whoever feeds on this bread will live forever.” (John 6:53-58, ESV)
Returning to the Feast of Passover now, first the people of Israel applied the lamb’s blood, representing Jesus, to the door posts of their houses. Later they wrote Jesus’ words upon their homes. These actions symbolically and prophetically represent spiritual salvation through the blood of Jesus, which reconciles us to God, and then soul salvation by eating Christ’s blood (applying Jesus’ words to our lives) which brings us into the full status of being a son of God.
Now recall what Peter says concerning us, “Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.” (1 Peter 2:5 KJV) And consider what Hebrews says concerning this:
Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus; Who was faithful to him that appointed him, as also Moses was faithful in all his house. For this man was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house. For every house is builded by some man; but he that built all things is God. And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after; But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end. Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: When your fathers tempted me, proved me, and saw my works forty years. Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways. So I sware in my wrath, They shall not enter into my rest.) (Hebrews 3:1-11 KJV)
The passages directly above thus show us that even the houses in ancient Israel prophetically pointed to each of us individual believers in God (Jesus Christ). We become believers when we believe that Jesus died for our sins and shed his blood for our reconciliation with God. We eat his blood (spiritually) when we eat his words, when we assimilate his words into our lives and make them part of us. This is a progressive salvation. It begins in our “most holy place,” our spirits, and moves outward to what is supposed to become our “holy place,” our souls. The final, or third salvation, is the salvation of our bodies which occurs at our glorification, our resurrection from the dead. This can only occur after we each achieve the second salvation (the one of which Paul says, “work out your salvation in fear and trembling”). Jesus Christ has already effected the first salvation, but most people remain in the prison of their unbelief and cannot begin to walk the path of “becoming” a son of God yet.
God guarantees all men the salvation of their spirits, although few have understood this presently. Consider the following verse which I believe irrefutably proves this. “For as in Adam all die, so also in Christ shall all be made alive.” (1 Cor. 15:22) Clearly it is the same “all” who die in Adam who shall be made alive in Christ. It makes no sense to say that this refers to two different groups of people or to say that Paul really meant to add the words “who believe in Jesus Christ as Savior” after the second use of the word. (What exactly was it that God said would happen to people who added to Scripture? Look it up if you can’t remember!)
Now look at a couple obscure verses from the Gospel of John. Just before Jesus’ betrayal he said, “While you have the light, believe in the light, that you may become sons of light.” (John 12:36) In the beginning of his book John said, “to all who did receive him, who believed in his name, he gave the right to become children of God.“ (John 1:12) Both Jesus and John make the point that believing in Jesus as Savior is only the beginning. That is the step that everyone must take before he can even begin to walk on the path to “becoming” a son of God.
So, if believing in Jesus as Savior (putting the lamb’s blood on our door posts) only gives us the initial right to become a son of God, what must we do make it a reality? We must also “drink” that blood… we must write his word on our door posts as well.
