This sermon explores the biblical feasts of Pentecost and the Feast of Trumpets, examining their historical significance and prophetic fulfillment in Christ. The pastor explains how Pentecost celebrated the completion of the harvest and God's provision, while also pointing to the future outpouring of the Holy Spirit and the inclusion of all nations in God's plan. The Feast of Trumpets served as a spiritual alarm, calling people to remember God as King and prepare their hearts. Both feasts find their ultimate fulfillment in Jesus Christ - Pentecost through the outpouring of the Holy Spirit in Acts 2, empowering believers to be witnesses to all nations, and the Feast of Trumpets through Christ's kingship and His promised return. The message emphasizes that God's plan always included all nations, both Jew and Gentile, and calls believers to embrace their role as witnesses empowered by the Holy Spirit.
