Celebration and Repentance

Today is Yom T'ruah, or Rosh Hoshanna. You can Google it for yourself, but here are a couple of sites that I found with some explanations. This one is audio.

What I could understand is that it is a day to celebrate the next 10 days of reflecting on your spiritual condition to prepare for atonement. Whenever this horn was blown it was for specific reasons and everyone's attention given. Some info on the shofar horn said that it may have also sybolized God's own voice.
Since Jesus the Messiah became my attonement, I appreciate the need for times of remorse for my daily sinfulness, remembering my unworthiness, because it draws me closer to my Lord. But God doesn't want us to "dwell" on this because He deserves my joy and gratitude for redeeming me in spite of all my garbage. I'm often overwhelmed with the realization that He has actually made me His precious heir, and that He has very intricate plans for my life.
