Christians go to church on Sunday and offer up worship service to God. Among them are some who appreciate the choir¡¯s songs, assess the representative prayer, and evaluate the sermon. They might think they are worshipping in church on Sunday, but are they really? If we truly offer up the service to God, we put our hearts in the choir¡¯s praise and offer them up to God. We consider the sermon to be the message given to us by God. Thus, we must be the worshipper.
