The shofar is a reminder of our covenant with G-d because of Abraham, Isaac and Jacob. When we hear the shofar we are to remember the binding of Messiah Yeshua, our ultimate Akedah. Messiah Yeshua was offered up as the Lamb of G-d who takes away the sin of the world on that same spot two thousand years later. When we hear the shofar we are to remember the shofar that accompanied the revelation of the giving of the Law on Mount Sinai, and that all Scripture is divinely inspired by G-d. 7. When we hear the shofar we are to remember the words of the prophets.
Prophets are like a shofar which warn of danger.
Israel was judged for ignoring the prophets. There is even greater judgement if we ignore Messiah Yeshua, Israel's greatest prophet. When we hear the shofar we are to remember the battle alarm for war. Messiah will return and fight during the greatest battle of all time, the battle of Armageddon. We are in the middle of a battle that has been raging for the soul of humanity.
