The Feast of Trumpets has a dual role, a memorial of God's past deliverance and a warning about future judgment. The Feast of Trumpets marks the third season in an annual spiritual cycle encapsulating: 1.) What God has done, deliverance from sin, 2.) What He is doing, Pentecost-transformation and growth, and 3.) What He will do—Christ's return and final judgment. The Feast of Trumpets (Yom Teruah, beginning the 10 Days of Awe) signifies a spiritual alarm, admonishing people to repent, reflect, and prepare for the coming Day of the Lord, a horrendous time of judgment, ushering in the return of Jesus Christ. Just as God commanded our ancestors on the Sinai to remember their deliverance from Egypt, God commands His people today to remember their spiritual deliverance from sin and Satan. II Peter challenges us to grow in Christ-like character, producing spiritual fruit and glorifying Almighty God. We must assiduously avoid drifting into spiritual complacency like the Laodicean church and the five foolish virgins. As Almighty God's people, we must secure our calling and avoid being unprepared when Christ returns.
