I have had the knowledge of the Feasts of the Lord for fifty-eight years.
The first two have been fulfilled by Jesus Christ, minutely in every detail. He was and is the Passover Lamb. This was fulfilled by His death on the Cross. He poured out the gift of the Holy Spirit on the Church fifty days later,thus fulfilling the Feast of Pentecost.
He has not, at this point in time, fulfilled the greatest feast of all, the Feast of Tabernacles. But He will, minutely, in every detail, prior to His Second Coming.
The pertinent section of Scripture is John 7:2, 37-39. And the Feast of the Jews, the Feast of Tabernacles was near. And in the last great day of the feast, Jesus stood and cried out, saying, If any anyone thirsts, let Him come to Me, and drink. The one believing into Me, as the Scripture said, Out of his belly will flow rivers of living water. See John 4:14 But He said this about the Spirit, whom the ones believing into Him, were about to receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified.
James 5:7 Therefore, brothers, be patient until the coming of the Lord. Behold, the farmer waits for the precious fruit, being patient over it until it may receive the early and latter rain.
Long patience! 2,000 years. Why? He is awaiting the FRUIT harvest (oil and wine). [The Church has received the grain harvests of barley (Passover) and wheat (Pentecost).
At this time Jesus will fulfill the Book of Revelation precisely, as He did the Gospels, (Passover), and the Book of Acts, (Pentecost)!
