The Feast of Trumpets teaches us that Jesus Christ will visibly return to the earth at the end of this age. At that time He will resurrect the saints who are no longer living and instantly change those saints who are still alive to immortal spirit beings (Matthew 24:31; 1 Corinthians 15:52-53; 1 Thessalonians 4:13-17). This festival commemorates the blowing of the trumpets that will precede His return. Seven angels with seven trumpets are described in Revelation 8-10. Christ will return with the blowing of the seventh trumpet (Revelation 11:15). The Feast of Trumpets depicts the return of Jesus Christ to earth to establish the Kingdom of God.
