This Psalm* is darker, in a minor key, kind of brooding and stern. What are we doing singing this kind of song in worship?
The book of Psalms gives us more moods to sing than just positive and encouraging, and we should use them. There is certainly a time to sing about nations rejecting our God and our Lord Jesus, these days. And the mood that brings is lament or stern resolution, not bounce and cheer. We should weep with those who weep in our singing together.
This can be tricky to engage with in worship. It takes some preparation. We don’t mentally veg out and just let the music float us down stream. One reason we have a printed bulletin is so you can look ahead a step or two and prepare for what is coming. Changing emotional gears can be a little abrupt sometimes. If it takes a verse or so to get into the new mood sometimes, that’s fine.
The key is this: are you singing the Word of God? Is the Word driving the words? Are we understanding and responding appropriately with our emotions to the Word of God as we sing?
No response at all or a deadpan is not appropriate. An artificial insistence on personal happiness isn’t appropriate, either.
Sing the Psalms with your whole heart and voice.
