1 Corinthians 15:51. As students of the Bible, we discover that the annual Jewish feasts were prophetic in nature. The spring feasts were fulfilled at his first coming, and the autumn feasts yet to be fulfilled at his return. The Feast of Trumpets will be fulfilled at the resurrection & translation of the saints. Now we are waiting, between the spring feasts fulfilled and the autumn feast fulfilments to come, for the trumpet to sound!
