Thanksgiving Begins with Self-Exhortation (v. 1)
David begins with a command directed inward: “Bless the LORD, O my soul: and all that is within me…” The phrase “O my soul: and all that is within me” reveals deliberate self-exhortation. David speaks to himself because he understands that the soul often needs to be awakened. Believers frequently preach to others while neglecting to preach to themselves. Here, David becomes both preacher and listener.
The expression “all that is within me” intensifies the command. Thanksgiving is not to be half-hearted or mechanical. God desires worship from the whole person, including all of the faculties of the soul, even mind, affections, will, memory, desires, and thoughts. Partial praise dishonours God, who gives complete mercy.
The entire self is to “bless the LORD”. By blessing the LORD, believers do not add anything to God, as if He lacks something, for God is eternally perfect, self-sufficient, and glorious in Himself. Rather, to bless the LORD is to speak well of Him, adore Him, praise Him, and consciously acknowledge His infinite worth and goodness.
Furthermore, David says, “bless his holy name”. God’s name represents His revealed character. It is the soul’s grateful response to who God is and what He has done. As we behold His holiness, goodness, mercy, and truth, our hearts are moved to worship. God’s holy nature alone makes Him infinitely worthy of all praise and thanksgiving. We do not wait for circumstances in life to be favourable before blessing God. We bless the LORD because He Himself is worthy.
Modern life often fragments our attention. Worship becomes distracted, routine, and hurried. Psalm 103 reminds believers that thanksgiving requires the gathering together of the entire inner man before God.
Thanksgiving Requires Remembering (v. 2)
David continues: “Bless the LORD, O my soul, and forget not all his benefits” (v. 2).
The repetition of “Bless the LORD, O my soul” again in verse 2 shows how easily our hearts drift from praise. Spiritual forgetfulness is one of humanity’s oldest sins. Israel repeatedly forgot God’s works (cf. Psalm 78:11, 106:13). Believers today do likewise.
“Forget not” does not suggest accidental memory loss but negligent disregard. Our lack of thanksgiving seldom arises from God’s lack of provision, but from our failure to remember His abundant mercies.
In Deuteronomy, God repeatedly warned Israel not to forget Him after receiving blessings (cf. Deuteronomy 8:11–14). Forgetfulness breeds pride, anxiety, and murmuring instead of humility and gratitude before the LORD.
When David speaks of “benefits”, he refers to God’s gracious bestowals. Every blessing comes from divine mercy. Psalm 68:19 says, “Blessed be the Lord, who daily loadeth us with benefits, even the God of our salvation” (cf. Deuteronomy 8:18; Romans 8:32). It is when we recognise that all we have received comes freely from His gracious hand that gratitude flows from our hearts.
Thanksgiving, therefore, involves disciplined recollection. Christians ought intentionally to recall God’s provisions, answers to prayer, preservation in trials, spiritual growth, deliverances, and daily mercies. A remembering soul becomes a thankful soul.
Thanksgiving Flows from God’s Saving Mercies (vv. 3–5)
David now lists specific reasons for thanksgiving. Significantly, spiritual blessings dominate the list.
He Forgives Completely
David begins with forgiveness because it reconciles us with God, which is one of the greatest blessings He bestows on us. It is therefore significant that he speaks of the comprehensiveness of God's forgiveness: "who forgiveth all thine iniquities". Sin is humanity's deepest problem, for it leaves every person guilty before a holy God. Such guilt cannot be removed by morality, religion, or self-improvement. Only God can forgive, and He does so abundantly through His gracious provision of pardon.
For believers reading this psalm in the light of the New Testament, this ultimately points to Christ’s atoning work. Through Him, forgiveness is full and permanent. A forgiven believer possesses an unshakable reason for thanksgiving even in affliction.
He Heals Compassionately
David’s words, “who healeth all thy diseases” (v. 3b), portray God more broadly as the source of restoration and preservation. He is not promising immediate physical healing from every sickness in this life.
Sin brought corruption into creation, but God remains the healer of His people’s bodies, minds and souls. Sometimes He heals immediately; sometimes gradually; sometimes ultimately in resurrection glory. Every recovery, preservation, and sustaining grace comes from Him.
Believers may therefore thank God not only for cures but also for sustaining grace amid weakness (Psalm 41:3; 2 Corinthians 12:9–10).
He Redeems Mercifully
“Who redeemeth thy life from destruction” (v. 4a). David recognised that apart from divine intervention, destruction awaited him. Time and again, God had preserved him from enemies, dangers, failures, and even the perilous consequences of his own sins. More importantly, David acknowledges that every deliverance, whether it be temporal, physical, or spiritual, was not by human strength but by God’s merciful and redeeming hand.
Every Christian has similar testimonies of God’s deliverance in life. God has rescued us from condemnation, eternal judgment, spiritual ruin, and countless unseen dangers in life. In modern life, this preservation and deliverance may be seen when God spares us from serious accidents on busy roads, protects us through dangerous illnesses, preserves us during surgeries and medical crises, provides unexpectedly during financial collapse or delivers us from situations that could have ended in tragedy. How many providential preservations remain unknown to us until eternity? Thanksgiving grows when we realise how much destruction God has prevented.
He Crowns Lovingly
God does not merely rescue sinners; He also enfolds them with covenant love: “who crowneth thee with lovingkindness and tender mercies” (v. 4b).
“Lovingkindness” speaks of God’s steadfast covenant mercy. “Tender mercies” remind us of His fatherly compassion. Believers are not merely spared from wrath; they are crowned with love and compassion.
What a remarkable image: sinners deserving judgment are adorned with grace. God does not deal with His children coldly or reluctantly, but surrounds them daily with His faithful care. His mercies sustain, restore, and assure us that our relationship with Him rests not on our worthiness, but on His unchanging love and covenant faithfulness.
He Satisfies Abundantly
Human hearts seek satisfaction in possessions, achievements, relationships, and recognition. Yet lasting satisfaction comes from God alone, “who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle’s” (v. 5).
David testifies that God fills His people with “good things”. These include daily provision of food and all other physical needs, as well as spiritual blessings. True satisfaction is not found in abundance itself, but in receiving God’s gifts with grateful hearts and resting in His sufficiency. “For he satisfieth the longing soul, and filleth the hungry soul with goodness” (Psalm 107:9; cf. Psalm 34:10b; Philippians 4:19).
As God nourishes His people physically and spiritually, He renews their strength for continued service, enabling weary souls to persevere with fresh confidence in His sustaining grace. This renewal, described as being “like the eagle’s”, symbolises divine refreshment and restoration of strength.
“...so that thy youth is renewed like the eagle’s” (v. 5). This vivid imagery speaks not of perpetual physical youthfulness but of God’s gracious renewal of strength and vitality. As the eagle soars with renewed vigour, so the Lord refreshes weary saints for continued obedience and service. Isaiah 40:31 echoes this promise: “they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles”.
Conclusion
Psalm 103 teaches us that thanksgiving is an active spiritual exercise in which we summon our souls to bless the LORD for all His benefits. Thanksgiving is spiritual warfare against irreverence, ingratitude, forgetfulness and pride. It is an act of faith that deliberately remembers God’s character and mercies.
When burdens dominate your mind, summon your soul.
When disappointments cloud your vision, summon your soul.
When blessings become ordinary, summon your soul.
When your spirit grows weary and forgetful, summon your soul.
Summon your soul to rise,
And give thanks unto God.
