We should not be concerned that we worship in the same way that God’s people worshipped five hundred years ago, a thousand years ago, or as they worshipped in the time of the early church. What needs to be added to worship that is not already a part of it? Yes, we may write hymns today that express a Biblical understanding of the work of Christ in the gospel, but we are not obsessed with continually inventing something new. We are content with hymns that were written hundreds of years ago, because the important elements of such hymns are things that do not change. The Scripture does not change and there is enough in Scripture to occupy us in study and in meditation all the days of our lives.
