Having worshiped with brothers & sisters in over 40 states, with focus on worship (especially in song) in Colorado, Nebraska, and Delaware, I am very much interested in your attempt as outlined above. Just need to have some of the terminology dealt with initially. First, what do you mean by “worship” songs? Where would “Where Cross the Crowded Ways of Life,” “He Bore It All,” “I Am Mine No More,” and “Now Thank We All Our God” fit–if they fit? Then, what is a “new” song? An “old” song? (Is date written the determining factor? Musical style? Congregational familiarity with it?)
Without having your answers, I could still be fairly confident in saying that the “one thing” you mention would include “heaven”–yet maybe not in the way you mean. We have a plethora of songs about the eternal home or ones that deal with some aspect of it, but most of these don’t have “worship” embedded within them and don’t do an effective job of drawing worshipers to worship.
Here’s trusting that your attempt to improve our assembly times will glorify the Father and will help all of us learn better how to adore Him. This “home improvement” project will take a lifetime and will never produce a finished structure, but your efforts may help us all do a better job of looking and reaching heavenward, “where Christ is seated at the right hand of God.”
Because of the One we revere,
