The big picture
Psalm 103 begins with one person ordering his own soul not to forget and ends with all creation summoned into praise. Between those points, The Book of Psalms gives mercy dimensions too large for accounting and compassion a scale intimate enough to remember dust. Forgiveness is pictured as distance, mercy as height, human life as grass, and divine care as a father’s pity. The chapter never treats frailty as a surprise to the Creator. He knows the frame he made and remembers what it is made of. Yet the same poem that speaks tenderly of dust also speaks of covenant, commandments, righteousness, angels, and a throne over all. Personal gratitude grows outward until it finds its place inside the whole dominion.
Central truth
Psalms 90 and 103 set brief human life against God’s everlasting life and mercy, teaching generations to remember that people are dust and grass while the Lord remains faithful.

What to explain, in order
Teach the passage in this order. Each step names the verses it rests on, so every point can be shown in the text before it is applied.
Psalms 90 and 103
Brief lives and everlasting mercy
Begin by explaining that Psalm 90 is headed A Prayer of Moses the man of God, which would make it the oldest psalm, and that it opens the fourth book of the Psalms after the collapse of David's line mourned in Psalm 89. Psalm 103 is a psalm of David. Teach them together because they look at the same truth from two sides: human life is short and marked by sin, and God is eternal and full of mercy. Psalm 90 asks for that mercy; Psalm 103 blesses God for it. Tell the class you will move from the prayer to the praise.
Psalm 90:1-6
Before the mountains
Read verses 1-2 and explain dwelling place as home, refuge, the place where a family lives through every generation. Explain from everlasting to everlasting. Then read verses 3-6 and let the contrast land. God turns man back to dust, as in Genesis 3:19. A thousand years are like yesterday or a watch in the night to him, as 2 Peter 3:8 recalls. People are swept away as by a flood, like a dream, like grass sprouting in the morning and withered by evening. Teach this honestly, with care for the bereaved.
Psalm 90:7-12
Secret sins, numbered days
Now teach the hard middle. Explain that the psalm links our brevity to God's anger at sin: our iniquities are set before him, our secret sins in the light of his face. Explain verse 10, threescore years and ten, seventy, perhaps eighty, as an observation of human life span, full of labour and sorrow, quickly gone. Then teach verse 12 as the prayer that arises: teach us to count our days so that we gain a heart of wisdom. Explain that wisdom here means living rightly before God in the time we have.
Psalm 90:13-17
Establish the work of our hands
Teach verses 13-17 as a turn from confession to petition. Moses asks God to return and have compassion, to satisfy them early, in the morning, with his mercy, so that they can be glad all their days. He asks for gladness to match the years of affliction. Then he asks for God's work to be seen by his servants and his glory by their children. Finally, the beauty or favour of the LORD upon them, and the work of their hands established. Teach that the prayer turns the brevity of life into a request for lasting fruit.
Psalm 103:1-5
Forget not the benefits
Turn to Psalm 103. Explain that David speaks to his own soul, bless the LORD, O my soul, and commands himself not to forget. Then teach the five benefits of verses 3-5 one by one. Explain that healing all diseases speaks of God as the source of every healing, and that Christians wait for its fullness in the resurrection, so it must not be used to blame the sick. Explain the eagle's renewed youth as vigour restored. Teach that forgetting God's benefits is the danger, and remembering them is the cure.
Psalm 103:6-18
Dust under compassion
Read verses 6-12. Explain verse 8 as the words God spoke to Moses in Exodus 34:6, merciful and gracious, slow to anger, plenteous in mercy. Teach verses 11-12: mercy as high as the heavens, transgressions removed as far as east from west, distances without end. Then verses 13-16: a father's compassion, God remembering we are dust, life like grass and a flower blown away. Then the great but of verse 17: mercy from everlasting to everlasting upon those who fear him, and his righteousness to children's children.
Psalm 103:19-22
One throne, many generations
Close with verses 19-22. The LORD's throne is in heaven and his kingdom rules over all. Then David calls angels, heavenly hosts and all his works everywhere to bless the LORD, and ends where he began: bless the LORD, O my soul. Teach that the psalm moves outward from one soul to the whole universe and back again. End the lesson by reading 90:1 and 103:17 together, so learners leave with the eternal God as their dwelling place and his everlasting mercy as their hope.
Where learners get stuck
The misreadings this passage tends to produce, and how to answer each from the text.
"Psalm 90:10 means I will live to seventy or eighty."
Verse 10 is an observation about the general span of human life, not a promise to any individual. Some die young and some live longer. The point of the verse is that even a long life is "soon cut off, and we fly away", so we should pray "teach us to number our days" (90:12). Be gentle with those who have lost children or young adults; the psalm does not say their loved ones were cheated.
"Psalm 103:3 means if I have faith I will always be healed."
The verse praises God as the one "who healeth all thy diseases", and every healing comes from him. But faithful believers in Scripture remained ill, like Timothy in 1 Timothy 5:23 and Trophimus in 2 Timothy 4:20. The full healing of all diseases awaits the resurrection. Never use this verse to tell a sick person they lack faith; use it to give thanks for every healing God gives.
"God is angry at us for being mortal."
Psalm 90 links our brevity to sin, as Genesis 3 does, but Psalm 103:14 says God "knoweth our frame; he remembereth that we are dust", and pities us "Like as a father pitieth his children" (103:13). God is not angry that we are weak; he grieves our sin and has compassion on our frailty. Teach both psalms together so that learners hear both the seriousness and the tenderness.
"If God removes my sin as far as the east is from the west, I can live however I like."
Psalm 103's mercy is "upon them that fear him" (103:11, 103:17) and "To such as keep his covenant" (103:18). Forgiveness is complete, but it is given to people who come to God in reverence and want to walk in his ways. As Psalm 130:4 says, forgiveness is given that God may be feared. Grace leads to gratitude and obedience, not carelessness.
Learning objectives
- Compare the grass imagery in both psalms.
- Connect mortality, sin, wisdom, and work in Psalm 90.
- List the remembered benefits of Psalm 103:3–5.
- Explain compassion through Psalm 103:13–14.
- Trace the concern for generations in both psalms.
- Interpret numbering days as a prayer for wisdom.
Teacher preparation
- Mark every reference to generations, years, days, children, dust, grass, and everlasting duration.
- Remember Psalm 90’s heading names Moses, fitting its wilderness-shaped concern with generations and wrath.
- Do not treat Psalm 90:10 as a guaranteed lifespan of seventy or eighty years.
- Compare Psalm 103:8 with Exodus 34:6 before class.
- Keep mortality and mercy together rather than letting either psalm cancel the other.
Evidence and interpretation checks
Explicit
Psalm 90:2 and Psalm 103:17 explicitly contrast human brevity with God’s everlasting life or mercy.
Scripture-supported
Psalm 90:8 supports a moral dimension because secret sins stand exposed before God.
Strong inference
Psalm 103:13–14 directly connects fatherly compassion with God’s knowledge that humans are dust.
Possible or traditional reading
Some read Psalm 90:10 as a fixed lifespan, but its poetry describes ordinary brevity and toil rather than a guarantee.
Limit
Neither psalm promises escape from death; they ask for wisdom, mercy, joy, meaningful work, forgiveness, and intergenerational faithfulness.
Discussion with answer guidance
1. Why call the Lord “our dwelling place” before discussing death?
What a good answer contains
Because the psalm establishes where security lies before it looks at human frailty. "Lord, thou hast been our dwelling place in all generations. Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God" (90:1-2). Only then, "Thou turnest man to destruction" (90:3). A good answer sees that Moses, to whom the heading attributes the psalm, starts with the eternal home of every generation so that death is faced from a place of safety. A weak answer starts with mortality and makes God an afterthought.
Show teacher guidance
Stability is located in God before human instability appears. Generations pass, but he does not.
2. Why do secret sins appear before “number our days”?
What a good answer contains
Because human brevity is bound up with human sin. "Thou hast set our iniquities before thee, our secret sins in the light of thy countenance" (90:8), and "all our days are passed away in thy wrath" (90:9). Then the prayer: "So teach us to number our days, that we may apply our hearts unto wisdom" (90:12). A strong answer sees that numbering our days means facing both how short life is and why, so that we live wisely before God. A weak answer reduces the verse to time management.
Show teacher guidance
The wisdom request follows moral exposure, so numbering days is more than time-management advice.
3. What does “establish the work of our hands” mean here?
What a good answer contains
It asks God to make lasting what would otherwise vanish. "And let the beauty of the LORD our God be upon us: and establish thou the work of our hands upon us; yea, the work of our hands establish thou it" (90:17). People whose days are grass ask that their labour have permanence because God confirms it. A good answer notes the repetition, which makes the request urgent, and sees that it comes after asking for God's mercy and glory to be seen by their children (90:14-16). A weak answer hears a prayer for career success.
Show teacher guidance
It asks God to give durable significance to work done by people whose own lives are brief.
4. Which benefits must the soul remember in Psalm 103:3–5?
What a good answer contains
Five benefits, each with a verb: God "forgiveth all thine iniquities", "healeth all thy diseases" (103:3), "redeemeth thy life from destruction", "crowneth thee with lovingkindness and tender mercies" (103:4), and "satisfieth thy mouth with good things; so that thy youth is renewed like the eagle's" (103:5). A strong answer notices that forgiveness comes first and that the list moves from rescue to honour to satisfaction. It should also handle healing carefully, since not every illness is cured in this life. A weak answer lists them loosely or skips forgiveness.
Show teacher guidance
Name forgiveness, healing, redemption, lovingkindness, tender mercies, and satisfaction with good.
5. How do father and child language work in Psalm 103?
What a good answer contains
"Like as a father pitieth his children, so the LORD pitieth them that fear him. For he knoweth our frame; he remembereth that we are dust" (103:13-14). Pity here is tender compassion. Then the children appear again: "his righteousness unto children's children; To such as keep his covenant" (103:17-18). A good answer sees that God's compassion is shaped by his knowledge of our weakness, and that his mercy passes from generation to generation. A weak answer imports a harsh picture of fatherhood, or forgets that the same psalm calls us dust.
Show teacher guidance
God pities frail people while mercy and righteousness extend to children’s children among covenant keepers.
6. What changes when both psalms use grass?
What a good answer contains
Psalm 90 says people are like grass that flourishes in the morning and is cut down by evening (90:5-6). Psalm 103 uses the same picture, "As for man, his days are as grass" (103:15), and then adds, "But the mercy of the LORD is from everlasting to everlasting upon them that fear him" (103:17). A strong answer sees that both psalms admit our brevity, and that Psalm 103 sets God's everlasting mercy against it, echoing the everlasting to everlasting of 90:2. A weak answer misses the shared image and the answer it receives.
Show teacher guidance
Psalm 90 stresses rapid withering; Psalm 103 adds that the Lord’s mercy outlasts the field.

Adapting the lesson
Children
Bring a flower or a few blades of grass, and a rock. Show the grass and say it fades quickly, then the rock, and say God lasts even longer than rocks and mountains (90:2). Teach 103:12 with arms stretched wide: as far as the east is from the west, God takes our sins away. Use 103:13 to talk about a loving father's care. Keep talk of death simple and gentle.
Youth
Ask what they would do if they knew how many days they had left. Read 90:12. Discuss how numbering days could change their choices about time, screens and relationships. Then read 103:1-5 and have them list benefits from God in their own lives. Use 103:12 for anyone carrying guilt. Be sensitive to anyone who has lost a friend or family member.
Adults
Give time to mortality and ageing, the death of parents and friends, and how adults face their own death. Discuss 90:17 and what it means for work to be established by God. Spend time on the father image of 103:13 for those whose earthly fathers failed them. Talk about remembering God's benefits as a discipline against grumbling and despair.
One to one
Ask where they are in life and what worries them about time. Read 90:1-2 and talk about God as their dwelling place. If they are grieving or facing illness, read 103:13-17 slowly. Help them list God's benefits in their own life, and pray 90:17 over their work and family.

Psalms 90 and 103
The passage in brief
Psalms 90 and 103 set our short lives against God's everlasting faithfulness. In Psalm 90 Moses says God has been our home in every generation, from everlasting to everlasting, while people fade like grass. He asks God to teach us to number our days and gain wisdom, to satisfy us with mercy, and to establish the work of our hands. In Psalm 103 David tells his soul to bless the LORD and not forget his benefits: forgiveness, healing, redemption, love and good things, mercy greater than our dust.
A verse to keep
So teach us to number our days, that we may apply our hearts unto wisdom.
