For five years, I cared for my friend Violet as her memories faded away. Dementia took hold, and the feisty Finnish woman who took pride in her nursing career, her spotless lawn, and her adoring German shepherd eventually forgot the people and home she loved. In her final months, she no longer recognized Bible verses that had buoyed her through so many storms.
But she still had “Amazing Grace.”
During Violet’s last year, I visited her every Tuesday with my Bible in hand. She neither recognized me nor recalled any words I read to her. But whenever I sang “Amazing Grace,” she joined in, warbling just as she had for so many years in the choir. In a season when the fog of dementia had otherwise clouded her vision of God’s grace, she reclaimed his promises through song: “I once was lost but now am found; was blind but now I see.”
Chorus of Commands
Throughout the Bible, praise, adoration, and thanksgiving move God’s people to sing. After God guides the Israelites safely across the Red Sea, Moses leads them in song (Exodus 15:1). When God protects David from Saul, David praises him with singing (2 Samuel 22:49–50).
This pattern repeats throughout the whole biblical story. When God blesses Hannah with a son, she sings in thanksgiving (1 Samuel 2:1–10). After Gabriel visits Mary to foretell Jesus’s birth, she rejoices with the Magnificat (Luke 1:46–55). Jesus himself sings a hymn (likely from Psalm 118) at the Last Supper (Matthew 26:30), and John foresees all the nations singing praises to the risen Lord in the new heavens and new earth (Revelation 5:9–12).
Paul encourages the church to “let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God” (Colossians 3:16). James writes, “Is anyone cheerful? Let him sing praise” (James 5:13). The Lord himself calls us to sing as we praise him. Consider Psalm 96:1–3:
Oh sing to the Lord a new song;
sing to the Lord, all the earth!
Sing to the Lord, bless his name;
tell of his salvation from day to day.
Declare his glory among the nations,
his marvelous works among all the peoples!
Psalm 147 likewise begins, “Praise the Lord! For it is good to sing praises to our God; for it is pleasant, and a song of praise is fitting” (Psalm 147:1). And Psalm 100 joins the theme: “Make a joyful noise to the Lord, all the earth! Serve the Lord with gladness! Come into his presence with singing!” (Psalm 100:1–2).
From beginning to end, singing and worship go hand in hand.
Reason to Sing
Why would God so fervently command us to unite our words with melody when we worship him? On the one hand, as God creates us in his image, we’re to rejoice in song just as he does. In Zephaniah 3:17, we read,
The Lord your God is in your midst,
A mighty one who will save;
He will rejoice over you with gladness;
He will quiet you by his love;
He will exult over you with loud singing.
Furthermore, when we lift our voices in song to the Lord, we direct our emotions heavenward, stirring up thankfulness in our hearts as befits the Almighty (Colossians 3:16). As Jonathan Edwards writes, “The duty of singing praises to God, seems to be appointed wholly to excite and express religious affections” (Religious Affections, 115).
And yet, there’s another reason to worship with singing — a reason beautifully evident during my visits with Violet. In Deuteronomy 31:19–21, God commands Moses to teach the people a song recounting his deeds so that they and their offspring might remember. “When many evils and troubles have come upon them,” God says, “this song shall confront them as a witness (for it will live unforgotten in the mouths of their offspring)” (Deuteronomy 31:21).
When we sing God’s praises, we glorify him, obey him, and direct our hearts toward him. But also, remarkably, we remember words our inconstant, sin-stricken brains would otherwise so quickly forget.
Musical Memory
The history of God’s people is a story of forgetfulness and remembrance. In the wilderness, the Israelites forgot the wondrous deeds God had accomplished in Egypt and worshiped the work of their own hands (Exodus 32:1–10). In the book of Deuteronomy, Moses pleaded with the people to remember what God had done for them (Deuteronomy 4:9; 8:2, 11–20). Joshua built a memorial of twelve stones from the Jordan River so the following generations might know how God provided (Joshua 4:1–7). Finally, in the upper room, Jesus commanded his disciples to take the wine and the bread in remembrance of him, as we also must do (Luke 22:19; 1 Corinthians 11:23–29).
To follow Christ is to remember and proclaim what he has done (Acts 4:20). And the gift of song, in addition to stirring our hearts, aids our minds in remembering. When we read a verse, it can flit away; when we sing it, we harbor God’s word in our heart (Psalm 119:11).
The link between song and remembrance arises from how God designed our brains. While the act of forgetting may seem simple, we actually have several types of memory, all organized within separate areas of the nervous system. Declarative memory involves recall of events, concepts, words, meanings, and facts, and it originates in the temporal lobes and hippocampus. Studies show, however, that music involves complicated networks in the brain beyond this system.
Singing triggers our procedural memory — a complex network involving the cerebellum, motor cortex, and deeper brain structures. Procedural memory allows us to perform actions without explicitly focusing on them. Consider how rarely you think about how to ride a bike or drive a car after your first awkward days of learning. Such procedural memories are so robustly imprinted in our brains, that we can take up an action like playing the piano or knitting even if we’ve not done so in ages.
Musical processing also connects to emotional memory, centered in a region of the brain called the amygdala. The emotional memory system helps us to recall events with strong feelings attached to them. The link between music and emotional memory explains why certain songs transport us to a specific moment in time and evoke feelings we may not have recalled for years.
Thanks to the connection between music and these two memory systems, we can hardly erase catchy jingles from our heads, no matter how much they annoy us. Hearing a familiar song on the radio can instantly carry us to that first handhold with a spouse or to our birthday party in kindergarten. Most stunning of all, the link between these systems reveals why the command to “Sing to the Lord!” not only glorifies God but also blesses us abundantly. When we sing, we remember.
Melody When Memory Fails
The human brain’s stunning ability to recall music is a gift of mercy in Alzheimer’s disease. Alzheimer’s preferentially affects the temporal lobes and hippocampus, the regions of the brain responsible for declarative memory. As a result, memory for language, names, and events erodes away. Memory for recent events fades first, as these are less rigorously stored. Over time, however, even remote events can slip away.
Memory for music, however, often remains intact in Alzheimer’s because it involves the procedural and emotional memory systems. The response to music is preserved even in advanced dementia, when patients can no longer reason, plan, or even speak. “I remember the first time I saw someone with Alzheimer’s remembering the Lord through music,” writes clinical psychologist Benjamin Mast in his book Second Forgetting: Remembering the Power of the Gospel During Alzheimer’s Disease. During his visit to a memory-care center, where “the full range of dementia was represented,” he writes,
When it came time for music, and especially the old hymns, things visibly changed. One woman who only wanted to leave finally sat down for a while to listen. A man who was always angry and agitated now had a contented look and tapped his foot to the music. Another man who was quite confused closed his tear-filled eyes and slowly raised his hands while quietly mouthing each word. God uses music to reach the seemingly unreachable. And he gives us this gift as a gracious resource to help us in drawing people back to him, to reengage their faith. (139)
By God’s grace, believers who can no longer remember the names of loved ones can still readily sing God’s praises. God has designed the very architecture of our brains to hide his word even when our memories fail. And he commands us to sing so that we might recall his life-giving word even when we’re prone to forget.
Sing to the Lord, my brothers and sisters. Make a joyful noise. And as you sing, even as other memories fade, remember his amazing grace — the breadth and length and height and depth of God’s love for you in Christ.
