I'm going to be the contrarian here. I think far too much time and effort is put into "matching" the hymns to the sermon. Do we "match" the prayers? Do we match the readings all the time? Biblical truth is so fundamental that there is almost always overlap.
I recall that you've posted along these lines before. If you don't link the hymns to the sermon and readings, how do you select the songs? And do you match the scripture reading(s) to the sermon?
I work with our music director to make sure that we sing a variety of selections - both a variety musically, and thematically. My preference is to have song selection done at least six months in advance (although often it can be three months).
I have several overarching principles:
- We sing four selections each Lord's Day morning. I try and have them be a variety of 2 hymns (RTH), one psalm, one contemporary song (which we have vetted and put into a Songbook we created)
- The first selection is nearly always what I call a "slam dunk hymn," one that everyone knows well (A Mighty Fortress, Crown Him with Many Crowns, etc.) that also sets the tone for opening worship (generally upbeat and praise of the Lord's attributes)
- The second selection occurs either right before or right after our Confession of Sin, so it is generally something thematically related to confessing sin or assurance of pardon. Psalms and many contemporary songs (the best of which are Psalm related) are excellent here.
- I try not to have more than one unfamiliar song (whether by words or tune) each Lord's Day.
I keep a spreadsheet of which songs we have sung over the past (now) five years. I have found that when pastors just pick hymns each week, they unconsciously include their "favorites" over and over again, and even if they good selections, it gets wearisome. As an example, a former pastor of mine used to select "Be Thou My Vision" about every other month.
Hymnody (and Psalmody) in my mind serves two purposes: (1) to engage the congregation in the corporate aspect of worship (which should increase engagement in prayer, Scripture hearing, etc.) and (2) to broaden the horizons/perspective with some new selections. This is how I have been introducing the Psalter to our people.
So as you can see, I would rather spend my time thinking and preparing music selections on a broader/higher level than spend an hour of potential sermon prep trying to find the perfect hymn about God's sovereignty for this week's sermon (which likely will reoccur within 5-6 weeks anyway). I feel the same way about sermon titles, but that discussion is for another time.
