The Seven Feasts of Israel were moedim—appointed times—that God commanded His People to observe at certain points in the year.  They gave a structure to the lives of the Jewish people, as well as reminders that God had cared for them in the past and would do so in the future.  Just as we mark special days and events on our calendars, the Jewish people looked forward to these days of celebration, worship, repentance, and remembrance.  Though many centuries have passed since God instructed Moses to detail His plans to Israel, His calendar is not yet complete.
There are no events that take God by surprise because He knows the end from the beginning.  The spring feasts have been prophetically fulfilled, and the events they foretold have already come to pass.  As we look ahead to the fall feasts and the future they portray, we can be just as confident that God will keep all of His promises, and these events will come to pass as well.  He has a wonderful future in store for us that goes far beyond this life into a lasting and unbreakable fellowship and union with Him.  The feasts of Israel are a time for us to look not just at the past, but also at the future with an eager anticipation for what God has in store.
There is no doubt that we are living in a crisis moment where history and destiny intersect.  The signs are there for all those with eyes to see.  God has called us to take a stand in defense of His Chosen People in these prophetic days, and as we celebrate the feasts we are reminded of this promise from the Lord: “When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near” (Luke 21:28).
It was common during Bible times for a young Jewish couple to be betrothed to be married, followed by the departure of the prospective husband.  He would return to prepare a place for the new couple to live.  When it was done, he would come back for a great wedding feast, and then they would begin their lives together in their new home.  Jesus talked about this practice in the parable He told of the wise and foolish virgins—one group was prepared for the bridegroom to come, and the other was not.
There is a great feast being prepared for us…and God calls each of us to prepare ourselves well.  That way when we see Him, we will not be ashamed.
The twenty-four elders and the four living creatures fell down and worshiped God, who was seated on the throne. And they cried: “Amen, Hallelujah!” Then a voice came from the throne, saying: “Praise our God, all you his servants, you who fear him, both great and small!” Then I heard what sounded like a great multitude, like the roar of rushing waters and like loud peals of thunder, shouting:
 
Hallelujah! For our Lord God Almighty reigns. Let us rejoice and be glad and give him glory! For the wedding of the Lamb has come, and his bride has made herself ready. Fine linen, bright and clean, was given her to wear.” (Fine linen stands for the righteous acts of God’s holy people.) Then the angel said to me, “Write this: Blessed are those who are invited to the wedding supper of the Lamb!” And he added, “These are the true words of God” (Revelation 19:4-9).
