After the return of Jesus Christ to earth, people will keep God's annual Feast Days, especially Tabernacles. This will observe this holy time EVERY year during our Lord's millennial reign (Zechariah 14:16).
Jesus will set up God's Kingdom at his second coming and usher in the Millennium, which is what the Feast of Tabernacles foreshadows (Isaiah 2:2 - 3). This joyous Feast period is one of three any festivals God commands ALL believers to keep each year.
Celebrate three festivals a year to honor me . . . Celebrate the Festival of Shelters in the autumn, when you gather the fruit from your vineyards and orchards. (Exodus 23:14, 16)
This holy period, like all of God's annual convocations, is designed so that the whole family may rejoice together. In fact, our heavenly Father COMMANDS that we rejoice during this happy period (Deuteronomy 16:13 - 14).
Special Sacrifices were offered on each day. Additionally, special Psalms were sung during the Feast. These were Psalms 120 to 134, known as the fifteen "songs of degrees," or "songs of ascent." They were sung by pilgrims on the way up to Jerusalem. Psalms 113 to 118, known as the Hallel (Praise God) Psalms, were also sung.
Without a doubt, Jesus kept this holy period of worship and rejoicing while he was on the earth (John 7:1 - 2, 14).
The Apostle Paul kept this holy period as well. When in Ephesus, he made every effort to quickly leave the city and travel, by boat, to Jerusalem in order to keep Tabernacles (Acts 18:19 - 21).
The Feast of Tabernacles will, most certainly, be kept in the future.
Likewise the people of the land shall worship at the entrance to this gateway before the Lord on the Sabbaths and the New Moons . . . But when the people of the land come before the Lord on the appointed feast days . . . (Ezekiel 46:3, 9)
According to Alfred Edersheim's book on the Temple, the keeping of Tabernacles is the most joyful of all God's holy days. The harvest in the fall was a reminder of Israel's dwelling in booths after the Exodus and the final harvest when its mission is complete and all people come to God.
The Last Great Day
The Last Great Day is also known as the eighth day. It is an independent festival from Tabernacles.
The Festival of Shelters begins on the fifteenth day of the seventh month and continues for seven days. On the first of these days come together for worship and do none of your daily work. Each day for seven days you shall present a food offering. On the eighth day come together again for worship and present a food offering. It is a day for worship, and you shall do no work (Leviticus 23:33 - 36)
Jesus kept the Last Great Day. It symbolized his ultimate offering, to all humans who have ever lived, the chance to repent and live forever with their Creator (John 7:37).
The Last Great Day has its own symbolism apart from the Feast of Tabernacles. It represents the time when God will make salvation available to all those who never had a previous chance to choose it (Revelation 20:4 - 5).
