During the program planning, all program points must be reduced and restricted (or even deleted) due to time constraints. Otherwise, the program would become much too long. Therefore, we must also limit the singing. However, we consider praising God through music an essential part of worship, and, in order to reserve enough time for singing, we hold song service ten minutes before every main event. Of course, we cannot avoid the disturbance of people coming in during this time, but try our best by inviting all participants to be in attendance ten minutes ahead of each main event to praise God in song.
