The third holy day season comes with the large fall harvest. Unlike the two spring festivals, God will use the third fall festival season to usher in major events that Christians are still waiting for. There are no Bible verses to confirm these upcoming events will happen on the festival’s exact days, but if God continues on his established pattern, there can be little doubt the fall holy days will play a prominent role in delivering his salvation to humanity. The next big thing most Christians are waiting for is the return of Jesus. When he returns his dead believers will be resurrected to eternal life. Deposing all worldly kings, Jesus will bring God’s law and kingdom to rule the earth. He will be heralded back with a great trumpet blast. Named the Day of Trumpets, God gave little reason for why he instructed the Israelites to celebrate the next holy day by blowing trumpets but he later had Ezra reintroduce his forgotten laws to them on the day of Trumpets, the first holy day of the fall festival season. 

 Corinthians 15:23-26 New Century Version
23 But everyone will be raised to life in the right order. Christ was first to be raised. When Christ comes again, those who belong to him will be raised to life, 24 and then the end will come. At that time Christ will destroy all rulers, authorities, and powers, and he will hand over the kingdom to God the Father. 25 Christ must rule until he puts all enemies under his control. 26 The last enemy to be destroyed will be death.

1 Thessalonians 4:16 King James Version
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:

Leviticus 23:23-25:46 International Children’s Bible The Feast of Trumpets
23 Again the Lord said to Moses, 24 “Tell the people of Israel: ‘On the first day of the seventh month you must have a special day of rest. There will be a holy meeting. Blow the trumpet for a special time of remembering. 25 Do not do any work. And bring an offering made by fire to the Lord.’”

Nehemiah 8:3 New Century Version
3 At the square by the Water Gate Ezra read the Teachings out loud from early morning until noon to the men, women, and everyone who could listen and understand. All the people listened carefully to the Book of the Teachings.

When we study like a Berean, and derive our information about God from the Bible like a Biblist, we know Jesus will return. He will put all enemies under his feet and his return will usher in a Kingdom that will have no end. It will happen here on this physical earth and it will rule over physical people. In time, all who have ever lived will be offered salvation. Their decisions will be honored forever. Accepting Jesus and salvation will be up to them. Do you believe Jesus will return? What better time than on God’s holy day? What other significance might the day of Trumpets have?
