Leviticus 23:1-44
In this chapter, the Lord proclaimed seven feasts that the children of Israel must observe. Each feast began with a sin offering to be followed by a burnt offering. God had declared that the burnt offerings were just as holy as were the sin offerings. Leviticus 6:17 (KJB). For the forgiveness of his sins, an Israelite could bring a clean animal to the priest for a sin offering or for a burnt offering. Leviticus 5:5-10 (KJB). This fact had to have meant that the burnt offering had a precise purpose just as did the sin offering.
The first and second feasts which the Lord commanded was the Passover feast which was a sin offering to be immediately followed by a burnt offering. Exodus 12:1-13 (KJB). Since the sin offering symbolized salvation by grace through the shed blood of Christ on the cross, then the burnt offering had to have symbolized the descent of the Spirit of Christ into Hell to leave behind there all of the sins, evil, and spiritual deaths of all living humans who would not become saved by grace. Acts 2:25-31 (KJB). The Israelites were to eat unleavened bread for seven days and offer burnt offerings. Unleavened bread symbolized the purity of Christ, and so the people were purified from all sin and evil by either the sin offering or the burnt offering. They were to do no work during these seven days to make them realize that God would save them by the sin offering or the burnt offering given by God on their behalf and not by any efforts of their own. God will save His entire living human race whom He creates and loves through either His sin offering or His burnt offering. I Corinthians 13:8 (KJB).
God commanded the third feast to be a "sheaf of the firstfruit of your harvest" for the priest to wave before the Lord. This had to be a symbolic representation of the resurrection of Christ. On that same day, they were to offer a burnt offering to the Lord which had to symbolize the immaculate ascent of the Holy Spirit from Hell to reanimate the perfect body of Jesus so that He could rise from the dead victorious over all sins, evil, spiritual death, and the Devil. II Timothy 1:10; Revelation 1:17-18 (KJB). Christ will save the entire living human race, some by His grace and all others in the end of the world. John 5:24; Revelation 5:11-14 (KJB). The Israelites were to also offer a meat offering followed by a burnt offering. They were to eat a part of the meat offering to symbolize that all living humans saved by grace would become indwelt by the Holy Spirit the moment that they repented and believed in Christ. Leviticus 6:14-18; John 5:24 (KJB). They were to also drink some wine which symbolized the fact that all living humans saved by grace would be washed clean of all sins and evil by the shed blood of Christ. Matthew 26:28; Revelation 1:5 (KJB). They were to also eat no ordinary food on that day until after they had made the meat offering, which was a type of the sin offering, and the burnt offering which symbolized that they all would be saved by God's work on their behalf and not by any efforts of their own.
Fifty days after the third feast, the Israelites were to observe the fourth feast. They had to eat a new meat offering, but this time baked with leaven. The leaven symbolized that living humans saved by grace could still sin in their fleshly natures even though their souls and spirits had been washed clean of all sins and evil by the blood of Jesus. Romans 7:18 (KJB). They were then to offer burnt offerings which were equal in importance to the meat offering and the drink offering. They both made a "sweet savour" to the Lord which meant they were of equal importance. The priests were then to repeat the sin offering as the blood sacrifice of clean animals. The harvest of the Israelites symbolized God's total salvation. God commanded that the "poor" and the "stranger" be allowed to glean some of the wheat that the harvesters were to leave for them on purpose. This symbolized that God intends to save the entire living human race.
In the fifth feast, God ordered that trumpets be blown to symbolize that God will regather all of the people of Israel back to the land that He has given them. Isaiah 27:12-13 (KJB). On that day, only the burnt offering was to be made. This burnt offering followed the second sin offering of the fourth feast. Just as the second sin offering of the fourth feast symbolized salvation by grace connected to the resurrection of Christ, so the burnt offering of the fifth feast symbolized the resurrection of all of the Israelites from their graves and the restoration of the nation of Israel with its citizens being every Hebrew who ever lived. Ezekiel 37:11-14; Romans 11:26-27 (KJB). Just as Christ will save every Christian in the Church Age in the Rapture of the Church because He will cause all backsliders to repent, so Christ will cause all Hebrews to repent in His final resurrection in the end of the world. Ephesians 5:25-27; Romans 11:26-27 (KJB). But just as the gleanings in the harvest will also be for the "poor" and the "stranger," and Joel prophesied that God "will pour out My Spirit upon all flesh," so God will save all of the Gentiles in His final resurrection in the end of the world. John 5:28-29; Revelation 5:11-14 (KJB).
In the sixth feast, a second burnt offering was to be made that also followed the sin offering of the fourth feast. The sixth feast symbolized that just as God will cause all Christians to repent and believe, so He will cause all Israelites to repent and believe. The sin offering always symbolized God's salvation by His grace which will be both Jews and Gentiles, and the burnt offering always symbolized God's lesser form of salvation in His resurrection of both repentant Jews and Gentiles in the end of the world. Christians go straight to Heaven when they die, but God will recreate the Jews and Gentiles of the final resurrection to a new life on His new earth. Revelation 21:1-5 (KJB).
In the seventh feast of Tabernacles, only a burnt offering was to be made which also followed the second sin offering of the fourth feast. This feast symbolized the eternal joy and peace that all living humans saved by grace will experience in Heaven, and the eternal joy and peace that all recreated humans will experience in their eternal lives on God's new earth. The believers in Heaven will enjoy being possessed by the very righteousness of Christ Himself, and the saved of the earth will enjoy their possession of the recreated life of righteousness that God gave to Adam and Eve before they sinned. II Corinthians 5:21; Revelation 21:1-5 (KJB).
