Teshuva Brings Meshiach

The gemora in Rosh Hashanah says that we blow twice before musaf and by musaf to cinfuse the Satan. How, explains the Haflaah that by blowing extra we show our love to Hashem and our teshuva becomes one of ahava, from love which converts our sins to benefits, so the yetzer hara gets cinfused. What should he do? Mention avonos, intentional sins, they will become benefits.
Tosfas says that he thinks that the shofar is Meshiach’s shofar, why now? It says גדולה תשובה שמביאה את הגאולה, teshuva is great because it brings the redemption and it also says גדולה תשובה שמקרבת הגאולה, teshuva is great because it accelerates the redemption. Explains the Ksav Sofer, it says בעתה אחישנה, in its time it will be accelerated. Why accelerate by its time? There are two times when the redemption can come, in its fixed or in the accelerated time. הנסתרות לה’ אלקינו the fixed hidden time, we have no control over it only Hashem but הנגלות לנו ולבנינו וכו’ לעשות את כל דברי התורה הזאת but the accelerated time is in our hands by keeping the Torah. Teshuva will be done from fear, forced on us when the fixed time for redemption arrives. However, when we do teshuva from love and follow the Torah, the redemption will come before the fixed time. Maybe, as we said from the Haflaah that blowung extra is considered doing teshuva from love, si the Satan thinks that we are accelerating the coming of the Meshiach and the sound of the shofar is a signal for its coming.
