The Jewish Feast Days were given to Moses on Mount Sinai. They are days appointed by God for the Jewish people, but they have a great deal to do with the Christian Church and the whole world.
As you can see from the chart, the days have been divided into Spring and Fall feast days. The Jewish Passover was prophetically filled on Good Friday with Jesus’ death on the cross. The Feast of Unleavened Bread represents Jesus’ burial and the Feast of First Fruits has to do with His resurrection. Jesus is the first fruit of the resurrection. Those who believe in Him will follow. Pentecost celebrated the giving of the Law of Moses. It is also the prophetic fulfillment of the outpouring of the Holy Spirit, when God would write His law on our hearts. This date also marks the beginning of the Church.
The Fall feasts of Trumpets, Day of Atonement, and Tabernacles have not yet been fulfilled prophetically, though some might argue that Jesus’ birth was a fulfillment of Tabernacles. Tabernacles signified God’s dwelling with His people and that will not occur until the Second Coming and the Millennial Reign of Jesus Christ. The Feast of Atonement could very well picture the Second Coming of Jesus Christ.
