Summer festival:
The one Jewish festival all by itself is Pentecost, the Feast of Weeks. Pentecost is also referred to as Rosh Hashanah. Pentecost occurs 50 days after Passover, hence its name, and sometime in March or April. In 33 AD this feast of the Lord was when the Holy Spirit first descended from heaven to indwell all believers which ushered in the time of the Gentiles, what we refer to as the church age. The original “Pentecost” was when Moses went to the top of Mount Sinai to receive God’s law. On the first Pentecost after the ascension of Jesus there were numerous conversions to Christ, water baptisms and fulfillment of the promise of the infilling of the Holy Spirit. This represents the three primary messages that we are to preach: go into to all the world and preach the gospel, baptize believers in water and encourage believers to receive the baptism of the Holy Spirit by accepting Jesus Christ as their Lord and Savior.
The power of the Holy Spirit authenticated the resurrection of Christ at Pentecost by empowering all believers, especially the disciples, to spread the gospel to all nations. After the infilling of the Holy Spirit the timid disciples were turned into lions of the faith who preached to all the world. All the disciples except John were martyred for preaching the gospel of Christ. The church was anointed on Pentecost and assigned to spread the “good news” of salvation to all nations. Once the Jews crucified Jesus, their promised Messiah, God turned to the Gentiles to spread the gospel of Christ. Two God days of 1,000 years each (2,000 years) were assigned to the church age so the time of the Gentiles is over at Pentecost in 2033 but does not officially end until the church is raptured four months later during the Feast of trumpets. This will fulfill the prophecy of Hosea 6:2. Again we see the parallel between an Old Testament feast of the Lord and the coming of Jesus into the world to save us from our sins. All of the Hebrew feasts were established by God to point to the coming of Jesus Christ. Some historians believe Jesus died in 32 AD and not 33 AD which, if true, would throw all my dates off by a year.
