What does the Bible say happened when trumpets blew?
Isaiah 58:1
1 Cry aloud, spare not, lift up thy voice like a trumpet, and
shew my people their transgression, and the house of Jacob their sins.
Trumpets point to a prophetic voice. A word. And shew my people. Would that word "shew" speak of revelation?
2 Yet they seek me daily, and delight to know my ways, as a nation that did righteousness, and forsook not the ordinance of their God: they ask of me the ordinances of justice; they take delight in approaching to God.
Here's a people who take delight in approaching to God, but they still have sin on their lives. Therefore, a trumpet is to sound. God said to Isaiah, "Lift up your voice like a trumpet and show them their sin."
So here is a revelation. The way we would apply that in our day since redemption has happened is to show people our sin in Him. He became sin for us. That would take care of sin in your life. This is the message all the way through the Scripture -- trumpets picture a showing or a revealing. It pictures something being seen that wasn't seen before. Look at first Corinthians chapter fourteen and we will see a New Testament place where Paul talks about trumpets.
1 Corinthians 14:8
8 For if the trumpet give an uncertain sound, who shall prepare himself to the battle?
God is sending a clarion sound through out the Church to explain to people their purpose in life. Your purpose in life is to grow up and be in His image.
This last set of three autumn feasts begins with TRUMPETS. And the three fall feasts speak of maturity in Christ. Trumpets begins this with a note of sounding revelation!
