In most basic terms, the Feast of Trumpets - the first of the three fall feasts - depicts the coming of the Messiah to rapture the Church and judge the wicked.
Some balk and argue that these feasts were given to Israel, not the Church, therefore, the Feast of Trumpets cannot depict the Rapture. In response, we make the following observations, to which many more could be added:

1. The Feast of Passover was given to Israel, but it depicts the Messiah's death on Calvary for the sins of the world. Clearly, its provision goes beyond Israel.

2. The Feast of Unleavened Bread was given to Israel, but it depicts the fact that the Lord's body would not decay in the grave. Again, crucial Church doctrine.

3. The Feast of Firstfruits was given to Israel. However, it depicts the Lord's triumphant Resurrection. It is because He lives that believers will also live.

4. Feast of Weeks (Pentecost) was given to Israel, but it depicts the birth of the Church through the New
Covenant. Believing Jews and believing Gentiles become one in the Messiah.

5. The Abrahamic Covenant (Gen. 12:1-3) was made with the father of the Jewish Nation, but it is the source and wellspring of every blessing the Church possesses.

6. The Davidic Covenant ( 2 Sam. 7:8-16) was made with Israel's king, but it is the basis of the Messiah's return as the Son of David and Lion of Judah to take His rightful throne as the King of kings and Lord of lords.

7. The New Covenant was made with Israel (Jer. 31:31; Mt. 26:28), but the Church has entered into its provision for salvation.

8. The Lord's Table was initiated with the elements of the Jewish Passover table with Jewish disciples, but it is one of the ordinances of the Church.

9. The command to evangelize the world was given to eleven Jewish disciples (Mt. 28:16-20, but it is commonly known as "the Great Commission of the Church."
