what does the bible say?
The seven Old Testament feasts God instituted as part of Mosaic Law point to Christ.
Jesus represented the Passover Lamb, the covering for our sin (Leviticus 23:5; John 1:29).
The Feast of Unleavened Bread pointed to Jesus’ sinless life and death for our sins (Leviticus 23:6; 1 Peter 1:19). Jesus was resurrected on the day of First Fruits because he was the first to defeat death through His resurrection (1 Corinthians 15:20). The Feast of Weeks, or Pentecost, was when Jesus sent the Holy Spirit (Acts 2), which was the starting point of the church.
The three fall feasts connect to Jesus’ second coming. Many connect the Feast of Trumpets to the rapture, when Jesus appears as He returns for the Church heralded by the sound of a trumpet (1 Thessalonians 4:13-18; 1 Corinthians 15:52). The Day of Atonement is when the Jewish remnant receives the Messiah (Zechariah 12:10; Romans 11:1-6, 25-36). Jesus has already made atonement for all believers; some believe this festival points to Jesus' second coming when atonement is fully realized and the Jewish remnant recognizes Jesus as Messiah.
Finally, the Feast of Tabernacles foreshadows Jesus’ second coming, when He will reign for a thousand years on Earth and ultimately live with His people for all eternity in the new heavens and new earth (Micah 4:1-7; Revelation 21:3-4). Jesus’ connection to the seven feasts shows, yet again, the coherency of Scripture.
