Spiritual Symbolism

The feasts are powerful symbols and standing memorials of Yahweh's plan of salvation for all men.
Starting at Passover, I would like to take the opportunity to share some thoughts that I have had concerning the meanings of these feasts. The following words are not inspired, but the correlation between these feasts and Yahweh's plan of salvation is very difficult to ignore.
Early in the book of Exodus, we learn that children of Israel were in bondage to slavery. Egypt represents the sin laden world and all its glory. We were in bondage, in slavery to satan while in our sins. Satan is the ruler and god of this world. Pharaoh is symbolically satan because Pharaoh ruled Egypt (symbolic of the world). Just as Pharaoh tried to destroy Israel, Satan also tries to destroy the predestined children of Israel lest we be large in number.
The children of Israel were oppressed and in the bondage of slavery to the Egyptians. The taskmasters, symbolic of demons (the servants of satan), afflicted those in bondage. The land flowing with milk and honey is symbolic of the "promised land", the eternal kingdom of Yahweh. Yahweh heard the cry of the children of Israel who wanted to be delivered from their bondage. We also knew the bondage that sin had brought upon us. We too, cried out to Yahweh. As we shall see, Yahweh delivered us in the same manner as He delivered Israel from their bondage.
Pharaoh did not want to let them go out of Egypt. So Yahweh sent plagues upon the Egyptians who worshiped idols. Yahweh showed His superiority over dumb idols by sending 10 plagues. Yahweh has revealed to us His superiority over the gods of this world whether they be lusts, pride, drugs, money or whatever sins might come between us and Yahweh. Just as He revealed to the children of Israel that He was all powerful and worthy of their faith, so He revealed Himself to us!
On the tenth day of the month of Abib, the lamb was to be set aside and examined for defects from Abib 10 to Abib 14. Yahushua the Messiah entered Jerusalem and went into the temple on Abib 10. He was on display until Abib 14. Just as the lambs of the children of Israel were required to be without spot or blemish, Yahushua, our lamb was totally without sin. The Lamb of Yahweh was examined many times by the chief priests and elders, as well as Pilate. When we examine Yahushua, we can see that He was without spot and without blemish. Even Pilate declared "I see no fault in him" (Luke 23:4, John 18:38, 19:4-6).
Consider also that to Yahweh a day is as 1000 years (Psalm 90:4). The Messiah was also hidden from the sight of man for 4 days (4000 years) until He became the Lamb of Yahweh.
So the whole assembly was to kill the lamb and place the blood on the lintel and doorposts of their homes. They would then eat the lamb. We must partake in the body and blood of the Lamb. It is not a literal flesh and blood (this would be an abomination), but flesh and blood symbolic of 2 things. Bread is also known to represent His word in scripture. The word of Yahweh convicts us of our sin and shows us our sin. Therefore we need redemption. This is why we take from the cup. It is the blood of Yahushua that covers and cleanses us from all sin.
Soon after the Passover, the children of Israel were baptized via the Red Sea and the Cloud and delivered from that old life of sin and bondage. We also were baptized into the name of Yahushua the Messiah and delivered from that old life of sin and bondage. After the Passover, we have the feast of unleavened bread. Throughout scripture, leaven represents sin. This represents the cleansing that Yahushua had done for us. Our house was cleansed from all iniquity.
Next, we have the feast of weeks, or Pentecost. This feast was the time that Yahweh is said to have spoken the commandments from Mount Sinai. It was also the time of the outpouring of Yahweh's Spirit in Acts 2. Indeed, Yahweh's word is Spirit!
Next, we have the feast of trumpets which may signify the Day of Yahweh when Yahushua will set up His 1000 year reign over all the earth. As previously mentioned, the trumpets were also used to advance the children of Israel to the promised land. We will enter the promised land at the "last trump".
The Day of Atonement, as we said can represent the atoning of all the world from sin and the penalty of sin, death. Finally, we will tabernacle with Yahweh forever and the last enemy will be defeated. Until then, we (like Israel) are in the wilderness and are being taught the law of Yahweh as we encounter tests, trials and tribulations. We will need to overcome and do so without murmuring or complaining if we expect to make it to the promised land.
Let's remember also that it was not Moses that ultimately brought Israel to the promised land, but his successor Joshua. What does this signify? Joshua is the same name in Hebrew as the name of the Messiah, Yahushua. I believe that it teaches us that although Moses can show us the way to enter the promised land, it takes a man named Yahushua to take us there. Even so, come Master Yahushua!
