The Strength You Need When Your Heart Fails
Text: Psalm 73 (ESV)
Introduction
Every believer eventually encounters something that shakes them.
Sometimes it isn’t a tragedy.
Sometimes it is simply looking around.
- Why do evil people seem to prosper?
- Why do faithful people struggle?
- Why does obedience sometimes appear unrewarded?
- Why does life seem unfair?
Those questions aren’t new.
Asaph asked every one of them.
Psalm 73 is remarkable because it is brutally honest.
Asaph doesn’t pretend to be stronger than he is.
He admits that his faith almost collapsed.
Yet by the end of the Psalm he makes one of the greatest declarations in all of Scripture:
“My flesh and my heart may fail, but God is the strength of my heart and my portion forever.” (Psalm 73:26)
That statement becomes the destination of the Psalm.
He didn’t begin there.
He journeyed there.
And often we do too.
I. Faith Can Be Shaken by What It Sees
Psalm 73:1–16
Begin with verse 1.
“Truly God is good to Israel, to those who are pure in heart.”
This is Asaph’s theological foundation.
He knows the truth before he begins telling the story.
Then verse 2 changes everything.
“But as for me, my feet had almost stumbled, my steps had nearly slipped.”
Notice:
- He did not lose his faith.
- He almost did.
- There is encouragement in that.
- Even mature believers experience seasons where faith feels unsteady.
What weakened him?
Verse 3.
“For I was envious of the arrogant when I saw the prosperity of the wicked.”
Notice the progression.
- He looked.
- He compared.
- He envied.
- Then he doubted.
Comparison has always been one of Satan’s favorite tools.
We compare:
- marriages
- finances
- ministries
- careers
- health
- opportunities
Comparison slowly shifts our attention from God’s faithfulness to someone else’s circumstances.
Asaph begins making observations.
He describes people who seem to have:
- healthy bodies
- plenty of wealth
- little suffering
- confidence
- influence
- pride
- no apparent consequences
To him, they seem to be winning.
Meanwhile, he has tried to honor God.
Yet his own life has been difficult.
Verse 13 summarizes his emotional conclusion.
“All in vain have I kept my heart clean and washed my hands in innocence.”
That is not theology.
That is emotion speaking.
#Virtualamen: One of the greatest dangers during difficult seasons is allowing our emotions to interpret God instead of allowing God to interpret our emotions.
- Circumstances are poor interpreters of God’s character.
- We cannot determine God’s goodness by today’s circumstances.
- We determine today’s circumstances by God’s revealed goodness.
Transition
Asaph’s problem wasn’t lack of information…It was limited perspective.
And perspective changes only in one place.
II. Strength Returns in God’s Presence
Psalm 73:17–22
Everything changes with one phrase.
“…until I went into the sanctuary of God; then I discerned their end.”
Nothing changed outside.
Everything changed inside.
This is the turning point.
Notice what happened.
- He entered God’s presence.
- God did not immediately remove the difficulty.
- God corrected his vision.
Worship restores perspective.
- God becomes larger,
- our problems become smaller,
- and eternity becomes clearer.
The sanctuary reminded Asaph:
- Life is longer than today.
- Justice is larger than today.
- God’s purposes are greater than today.
Eternity changes today’s calculations.
Asaph realizes that prosperity without God is temporary.
Difficulty with God is temporary too.
Everything looks different when viewed through eternity.
God’s truth corrected emotional conclusions.
Verses 21–22 are astonishing.
He confesses:
“When my soul was embittered… I was brutish and ignorant.”
That takes humility. Instead of accusing God, he recognizes that bitterness distorted his own thinking. Bitterness never improves our vision…It clouds it.
Application
- Most battles are not won by changing circumstances. They are won by entering God’s presence until our perspective changes.
- The greatest miracle God often performs is not changing the situation. It is changing the person facing it.
III. God’s Presence Is Greater Than Human Strength
Psalm 73:23–28
Now comes one of Scripture’s richest sections.
- Notice the repeated emphasis on God.
- Not circumstances.
- Not prosperity.
- Not answers.
- God Himself.
He Holds My Hand
“Nevertheless, I am continually with you; you hold my right hand.”
- Even when Asaph doubted, God never let go.
- Our grip on God may weaken. His grip on us never does.
He Guides My Life
“You guide me with your counsel…”
- God’s guidance is ongoing.
- He doesn’t merely rescue us.
- He walks with us.
- Even confusing seasons are not evidence of God’s absence.
- Often they are evidence that He is still leading.
He Is My Greatest Desire
Verse 25.
“Whom have I in heaven but you? And there is nothing on earth that I desire besides you.”
This is one of the highest expressions of spiritual maturity.
- Asaph began envying what others possessed. He ends treasuring God Himself.
- The greatest gift God gives us is not what He provides…It is Himself.
He Is My Strength
Now the climax.
“My flesh and my heart may fail, but God is the strength of my heart and my portion forever.”
He doesn’t say:
- “My body became stronger.”
- “My circumstances improved.”
- “My enemies disappeared.”
He says:
- “My heart may fail—but God will not.”
The Hebrew word translated strength carries the idea of a rock, a sustaining foundation—something firm that does not collapse under pressure. Human strength is limited. God’s strength is inexhaustible.
This is where the entire sermon series comes together.
- Isaiah 40 taught us that those who wait upon the Lord renew their strength.
- Hebrews reminded us that God strengthens weak hands and feeble knees.
- Now Psalm 73 teaches us that sometimes the greatest strength God gives is not strength for our bodies—it is strength for our hearts.
He Is My Inheritance Forever
“My portion forever.”
Everything else can be lost. Health, Money, Position, Relationships, Even life itself. But no one can take away God.
#Virtualamen: The believer’s greatest inheritance is not heaven’s streets of gold…It is the everlasting presence of the Lord.
Conclusion
Asaph’s journey is the journey of many believers.
He moved from:
- comparison to contentment,
- confusion to clarity,
- envy to worship,
- weakness to strength.
And what changed?
Not his circumstances.
His perspective.
He discovered that God’s greatest answer to a failing heart is not always immediate deliverance.
Sometimes His answer is His presence.
When your heart is overwhelmed…
When your faith feels weak…
When your emotions tell you God has forgotten you…
remember this:
“My flesh and my heart may fail, but God is the strength of my heart and my portion forever.”
That is the strength you need.
Because when God becomes our portion, we discover that His presence is enough, His guidance is sufficient, and His strength never fails. Even when our hearts do.
