We have already studied the first 4 feasts the Lord gave Israel, beginning with the Passover on the 14th of the 1st month. We saw how this Feast was a type and shadow of Jesus on the cross. The Pesach lamb's blood on the doorpost was the sacrifice for the Jews that night, but Jesus, our Messiah, was the Lamb of God, and He was the sacrifice for the whole world forever!
Following within hours of the Passover sacrifice was the beginning of the second Feast, Unleavened Bread, which lasted 7 days. Its purpose was separating the leaven from the old grain, and from their home. On a spiritual level, it speaks to the believer of sanctification by the Spirit; a life separated from the "leaven" of malice, hatred, envy, lust and other wordly appetites, and to be separated unto God.
The third feast was the Feast of Firstfruits, where the Priest waved a sheaf from the early barley harvest in thanksgiving, 3 days after Passover, immediately after Sabbath. It is a clear type of the resurrection of Jesus, who rose after 3 days in the grave, after Sabbath. His resurrection gives us hope of resurrection of the harvest of Saints that will follow when Jesus returns!
The fourth feast, the Feast of Weeks, which is to commemorate when God gave Moses the Law on Mt. Sinai 50 days after Passover. We saw how this date corresponed to what the church calls Pentecost, recorded in the book of Acts, and of how God poured out His Spirit, not on tablets of stone, but into the hearts of men and women who praised and worshipped and served Him! For the church, following in the steps of Jesus, it was the outpouring of the Holy Ghost, the Baptism of the Holy Spirit.
This brings us to the last 3 feasts, which are separated from the first feasts by a period of 4 months. By the numerical definition, #4 pertained to things created for man's use or benefit. During this period of time, the Jews made good use of the time to repair, mend, and work on family projects (build barns, or whatever they could before the last season of fruits and vegetables came and demanded their time to harvest). They needed this time to prepare for the next three Feasts as well. Part of that preparation was building a succot, a dwelling, as you see here, for the Feast of Tabernacles.
In a spiritual parallel, we see the Church in this time frame...having already experienced the first four Feasts of God's calendar; applying the blood of Jesus through the Passover; attempting to live a life separate from the leaven of the world after the waters of baptism have cleansed them from their sins; the Church saw His resurrection 3 days later, as the priest was waving the first fruit sheaf, and now, having experienced the Baptism of the Holy Ghost at the Feast of Pentecost, we are in that time period just before God turns the pages of the calendar on the next three prophetic Feasts.
The Church is now walking in His Spirit, operating in His gifts, spreading the Gospel, seeing the sick restored and the blind and crippled made whole, manifesting the good news by casting out demons and seeing lives filled with the overcoming power of the Holy Ghost. This is the time of preparation, because when the next Feast comes, it will be too late to work anymore. Church, this is the only time in the calendar of God, that we will have to reach and touch the lost!
The next three Feasts deal with the future. Like the first four, they are prophetic. It has been said that "if you want to know the future, you have to master the past." To know what lies ahead, you must understand the Feasts that God ordained in the past and see them through eyes of type and shadow.
