I joined in the local church worship team in Korea when I was in 9th grade. At first, I was very reluctant to accept the offer when the team leader asked me to play flute since I was not comfortable performing in front of people. However, I just decided to give it a try. I was very nervous and worried about making mistakes but my anxiety vanished after a couple of performances and I began to enjoy communication with people through music.
However, being the member of the worship team was not easy. Not only I had to put lots of efforts to prepare for the Sunday worship but also I had to dedicate my Saturday night for the team practice. Then why I continue with it?
It is true that myriads of practice might have worn me down. Nevertheless, when I was on the stage to lead the worship, my face lit up and I felt joy spreading through my body; all my complaints and weary thoughts just disappeared. On the stage, I could not find a shy girl once afraid of making mistakes but there was a girl who actually enjoyed performing in front of people. In addition, it was quite an amazing experience to see several distinct voices make a pleasant harmony.
Although I am now in American and I am unable to perform at my Korean church, I am playing flute as a member of school worship team and having a blessed time. Participating in the worship team has given and is giving me valuable lessons such as the importance of believing in myself and the greatest mistake that I often made was to continuously fearing to making one.
