Series: A person after God’s own heart (David) | 2 Samuel 12:1-14, Psalm 51:1-12 | Sunday 23rd August 2026 | Message by Pastor Rolly Stahl

I invite you to reflect on you own, or discuss with a friendly person:
How might people respond when “nailed” for a mistake or failure?
- We might blame others, lie about it, or deny it.
- We might make excuses for it, or justify it.
- We might try to minimise it: “Well at least I haven’t killed anyone!”
- We might point out the failures of the person confronting us, “Hey, what about the times you lied, stole, and got booked for dangerous driving!?”
The way a person handles failure reveals a lot about their character.
Let’s see what we can learn from David about two of his big blunders:
1. David’s adultery with Bathsheba and cover up
Instead of joining his men in battle, David was potting around his palace – perhaps feeling bored or restless. Once we lose sight of godly purpose in our everyday lives, we become vulnerable to temptation. As the old saying goes: “An idle mind is the devil’s workshop.”
From his palace roof, David saw Bathsheba bathing – and his desires were inflamed. He used his position to commit adultery with her. It’s ironic that David never lost a military battle; but he lost his battle with lust.[1]
When Bathsheba sent word to David that she’d fallen pregnant by him, David calls her husband, Uriah, back from the army, plies him with alcohol, and urges him to go home and sleep with his wife. That way, Uriah and others would assume the baby was his. But Uriah refuses.
When David asks him why, Uriah replied, “The Ark[2] and the armies of Israel and Judah are living in tents, and Joab and my master’s men are camping in the open fields. How could I go home to wine and dine and sleep with my wife? I swear that I would never do such a thing.” (2 Samuel 11:11 NLT)
Why does Uriah refuse to go home? Because his fellow soldiers are involved in a holy war. The army go out with the ark of the covenant – the symbol of God’s holy presence. Since God’s holy presence accompanies the army, all the soldiers need to be ceremonially clean – and that means no sex. Uriah swears on David’s life that he will not compromise himself, the army, or God by sleeping with his wife. Uriah’s devotion to duty highlights David’s self-indulgence.
Since plan A failed to cover up his moral failure, David resorts to Plan B. He arranges Uriah to be struck down in battle.
Then we read: When the period of mourning was over, David sent for her [Bathsheba] and brought her to the palace, and she became one of his wives. Then she gave birth to a son. But the Lord was displeased with what David had done. (2 Samuel 11:27 NLT) David didn’t just sin against other people. He also sinned against God.
Friends, no matter how hard we try to cover up our moral failings, God always sees it. God cannot pretend it doesn’t matter. Since God is perfectly good, holy, and just, he must deal with it. There are always consequences for breaking God’s commands.
The prophet Nathan presents a case to David for judgment. A poor man has one precious ewe lamb that’s like a member of his family. It ate from his plate and drank from his cup. He cuddled it like a daughter. Then there’s a rich man who has a visitor. Instead of taking an animal from his own vast flocks and herds, the rich man butchers the poor man’s pet lamb to feed his guest.
David’s anger hits the roof: “This man deserves to die!” With just four words, Nathan hits the bullseye of David’s heart: “You are that man!” “You have many wives, yet you took another man’s only wife and had her. When your efforts at cover up failed, you murdered her husband – and took his wife to be yours!”
Once confronted, there are 7 things David didn’t do:
1. He didn’t blame his upbringing: “As the youngest son, my big brothers picked on me.”
2. He didn’t blame other people: “I was under pressure from my advisors. I was under pressure from the competing claims of my wives and children.”
3. He didn’t blame his life circumstances: “Not being part of the war efforts against the Ammonites, I was having a mid-life crisis.”
4. He didn’t use past hurts to justify his actions: “After spending a decade on the run from Saul, I deserve a few kickbacks.”
5. He didn’t compare himself with others: “Other kings have done much worse things than I’ve done!”
6. He didn’t use his position as an excuse: “Since I’m the king, I can do as I jolly well please!”
7. He didn’t execute the prophet who confronted him.
Instead David “fessed up” to his failure
“I have sinned against the LORD.” (2 Samuel 12:13 NLT)
We even have a record of his confession in Psalm 51.
As I read some of it, note what David is asking God:
Have mercy on me, O God,
because of your unfailing love.
Because of your great compassion,
blot out the stain of my sins. (David knows that sin is stain on the soul that only God can remove)
Against you, and you alone, have I sinned;
I have done what is evil in your sight.
Create in me a clean heart, O God.
Renew a loyal spirit within me.
Do not banish me from your presence,
and don’t take your Holy Spirit from me. (like what happened to King Saul)
Restore to me the joy of your salvation,
and make me willing to obey you. (Psalm 51:1, 4, 10-12 NLT)
After David “fessed-up”, Nathan replied, “The Lord has forgiven you, and you won’t die for this sin. (2 Samuel 12:13 NLT) The Lord spares David’s life, takes away his sin, and restores relationship with David.
Now there were consequences of David’s actions: violence broke out in his family; four of his sons died prematurely; and one of David’s sons took his “wives”[3] and had them in public! Yet with the assurance of God’s forgiveness, David still gets to do life with God.
That same amazing grace is available for you and for me. By the blood of Jesus, shed at the cross, God has punished our mistakes – and blotted out the stain of our sins. Through his forgiveness, we still get to do life with God.
So friends, whenever you’ve done wrong, take a leaf out of David’s book. Confess it to God. Renounce it out of your life. Receive God’s forgiveness for Jesus’ sake. And keep asking the Holy Spirit to help you live in the love and truth of Jesus.
Here’s another mistake David made.
2. David took a military census
The king [David] said to Joab and the army commanders with him, “Go throughout the tribes of Israel from Dan to Beersheba and enroll the fighting men, so that I may know how many there are.” (2 Samuel 24:2 NIV)
Now the Lord could order a census of the Israelites. This happened twice in a book of the Bible called Numbers.[4] But if a king of Israel took a census, it was regarded as an act of pride in his army.
It was also considered an act of mistrust in God as Israel’s source of security. Even David’s ruthless general, Joab, objected: “May the Lord your God let you live to see a hundred times as many people as there are now! But why, my lord the king, do you want to do this?” But the king insisted that they take the census. (2 Samuel 24:3-4 NLT)
About 10 months later, Joab reported the numbers to the king. But after he had taken the census, David’s conscience began to bother him. And he said to the Lord, “I have sinned greatly by taking this census. Please forgive my guilt, Lord, for doing this foolish thing.” (2 Samuel 24:10 NLT)
Again David owns up, confesses his sin to God, and asks the Lord to forgive him.
Question: How can David so freely “fess up” to his failures?
Because he trusts that God’s mercy is greater than his sin!
Application:
There are 2 reasons why we avoid taking responsibility for our wrongdoing:
- Because like Adam and Eve, we strive to hide our guilt and shame.
- Because we’re not yet secure in God’s love for us in Jesus!
Follow the logic: If we’re not yet secure in God’s love for us in Jesus, we keep trying to secure ourselves. How?
- By making ourselves look good.
- By trying to impress God or others with our performance.
- Or by gaining our sense of worth from what we do …or what we own.
Since we can’t afford to “lose face”, we hide our guilt, shame, hurts, and insecurities under the “veneer” of success that we present to those around us.
But like corks that keep popping up in a bucket of water, our selfish attitudes, words, and behaviours keep surfacing. We keep messing up…but we hate to admit it!
So, when we’re confronted or challenged about “those corks popping up”, what do we do? Defend ourselves, justify ourselves, and attempt to make ourselves look good by minimizing the bad we’ve done.
Question: In ALL this, who is in the centre? SELF!! No wonder it’s a disaster! We were never meant to be the centre of our own existence! Truth is that we need God to free us from our self-centredness – AND from our failures that emerge from that.
Yet when our identity, worth, and self esteem
are based on God’s acceptance of us in Jesus,
our security in him frees us to acknowledge our mistakes
– without it destroying us!
Through the cross of Christ, we know that God’s mercy
is greater than our worst failures. So now we can come clean.
John reminds us: If we claim we have no sin, we are only fooling ourselves and not living in the truth. But if we confess our sins to him, he is faithful and just to forgive us our sins and to cleanse us from all wickedness. (1 John 1:8-9 NLT)[5] Friends, when God forgives us, he doesn’t rub it in. Instead, God rubs it out!
The aging Paul admits: “Christ Jesus came into the world to save sinners”— and I am the worst of them all.” (1 Timothy 1:15 NLT) If we can’t admit to being a sinner, then how can Christ save us? Like Paul, I’m a sinner… that’s why I need Jesus! He’s made it possible for us to become saints.
People after God’s own heart rest secure in his love and kindness to us in Jesus. Secure in God’s love, we can confess and renounce our failures, receive God’s forgiveness, and keep sharing his mercy with others! Amen.

[1] With David’s accumulation of wives and concubines over previous years, perhaps this indulgence was an accident waiting to happen.
See: 1 Samuel 25:39-44, 27:3, 30:5, 2 Samuel 2:2, 3:2-5, 5:13-16. On kings and numerous wives, see the prohibition at Deuteronomy 17:17. The outworking of the conflict among David’s children from these various wives is seen in 2 Samuel 13-19, and 1 Kings 1-2.
[2] The ark of the covenant. A transportable wooden box gilded with gold. The stone tablets of the covenant were inside the box. The atonement cover on top featured 2 cherubim facing each other. The Israelites understood that the Lord’s presence/throne was between the cherubim. Psalm 99:1 NLT: ‘God’sThe Lord is king! Let the nations tremble! He sits on his throne between the cherubim. Let the whole earth quake!’ (See: Exodus 25:22, Numbers 7:89, 1 Samuel 4:4, 2 Samuel 6:2, 2 Kings 19:15, 1 Chron 13:6, Ps 80:1, Isaiah 37:16)
[3] 2 Samuel 16:22 NLT: ‘So they set up a tent on the palace roof where everyone could see it, and Absalom went in and had sex with his father’s concubines.’
[4] Numbers 1:1-14, 26:1-4.
[5] Likewise, James says: Confess your sins to each other and pray for each other so that you may be healed. (James 5:16 NLT)
