"Sin's Deception and Consequences"

Proposition -In our text this morning we are going to see how unchecked sin crushes lives, families, and futures.

Interrogative Question - What are some specific desires or thoughts in your life that you need to guard against because they could lead to sin?

Sin always looks appealing at first—but it never shows you the full cost.

I. Sin Starts with Wrong Desires - vs. 1-5

2 Samuel 13:1–5 NASB95

1 Now it was after this that Absalom the son of David had a beautiful sister whose name was Tamar, and Amnon the son of David loved her. 2 Amnon was so frustrated because of his sister Tamar that he made himself ill, for she was a virgin, and it seemed hard to Amnon to do anything to her. 3 But Amnon had a friend whose name was Jonadab, the son of Shimeah, David’s brother; and Jonadab was a very shrewd man. 4 He said to him, “O son of the king, why are you so depressed morning after morning? Will you not tell me?” Then Amnon said to him, “I am in love with Tamar, the sister of my brother Absalom.” 5 Jonadab then said to him, “Lie down on your bed and pretend to be ill; when your father comes to see you, say to him, ‘Please let my sister Tamar come and give me some food to eat, and let her prepare the food in my sight, that I may see it and eat from her hand.’ ”

CSB Study Bible: Notes (Chapter 13) 13:1 David had several wives, and he fathered many children by them (3:2–5; 5:13–16). Both Absalom and Tamar had Maacah as their mother, whereas Amnon, David’s firstborn son, had Ahinoam as his mother. The words was infatuated with her may also be translated as “loved her,” but the present translation is better because Amnon’s actions toward Tamar show that he never really loved her.

The ESV Study Bible (Chapter 13) 13:1–2 Tamar was Absalom’s full sister and the half sister of Amnon, David’s eldest son. he made himself ill. Amnon’s “love” could better be described as “lust.”

The MacArthur Study Bible (Chapter 13) 13:1, 2 Tamar.“Palm tree.” She was David’s daughter by Maacah, the daughter of Talmai, King of Geshur (3:3), Absalom’s (David’s third son) full sister and half-sister of Amnon, David’s first son by Ahinoam (3:2). Amnon’s love for her was not filial, but lustful, as became clear in the story. Unmarried daughters were kept in seclusion from men, so that none could see them alone. Amnon had seen Tamar because of their family relationship and had conceived a violent passion for her. This was forbidden by God (see Lev. 18:11), yet with the example of Abraham (Gen. 20:12) and the common practice among the surrounding nations of marrying half-sisters, he felt justified and wanted his passion fulfilled with Tamar.

Amnon “loved” Tamar—but it wasn’t real love. It was selfish desire disguised as love.

He focused on what he wanted, not what was right

He allowed his thoughts to grow instead of stopping them

He listened to bad advice from Jonadab

Key Truth:

👉 Not every strong feeling is right. Feelings must be guided by God’s truth.

Illustration #1: The Spark

A small spark in a forest doesn’t look dangerous at first. But if it isn’t put out quickly, it can become a wildfire that destroys thousands of acres.

👉 Sinful thoughts are like that spark. If you don’t deal with them early, they grow out of control.

Application:

Guard what you think about (music, media, conversations)

Don’t entertain sinful fantasies

Choose godly influences—not “Jonadabs”

II. Sin Misguides and Hardens the Heart - vs. 6-14

2 Samuel 13:6–14 NASB95

6 So Amnon lay down and pretended to be ill; when the king came to see him, Amnon said to the king, “Please let my sister Tamar come and make me a couple of cakes in my sight, that I may eat from her hand.” 7 Then David sent to the house for Tamar, saying, “Go now to your brother Amnon’s house, and prepare food for him.” 8 So Tamar went to her brother Amnon’s house, and he was lying down. And she took dough, kneaded it, made cakes in his sight, and baked the cakes. 9 She took the pan and dished them out before him, but he refused to eat. And Amnon said, “Have everyone go out from me.” So everyone went out from him. 10 Then Amnon said to Tamar, “Bring the food into the bedroom, that I may eat from your hand.” So Tamar took the cakes which she had made and brought them into the bedroom to her brother Amnon. 11 When she brought them to him to eat, he took hold of her and said to her, “Come, lie with me, my sister.” 12 But she answered him, “No, my brother, do not violate me, for such a thing is not done in Israel; do not do this disgraceful thing! 13 “As for me, where could I get rid of my reproach? And as for you, you will be like one of the fools in Israel. Now therefore, please speak to the king, for he will not withhold me from you.” 14 However, he would not listen to her; since he was stronger than she, he violated her and lay with her.

The ESV Study Bible (Chapter 13) 13:12–13 such a thing is not done in Israel. Intercourse between brother and sister, even half brother and half sister, was forbidden in Lev. 18:9, and the stress on the outrageousness makes it seem likely that this prohibition was accepted at the time of David. he will not withhold me from you. Perhaps Tamar is saying that David would be willing to bend the rules, or perhaps she is just trying to escape.

The MacArthur Study Bible (Chapter 13) 13:12, 13 this disgraceful thing. Lit. “a wicked thing.” Tamar appealed to Amnon with 4 reasons that he should not rape her. First, it was an utterly deplored act in Israel because it violated the law of God (see Lev. 18:11) and Tamar knew that such action could bring disharmony and bloodshed to the king’s family, as it did. my shame. Second, as a fornicator, Tamar would be scorned as an object of reproach. Even though resistant to the evil crime perpetuated against her, Tamar would bear the stigma of one defiled. like one of the fools in Israel. Third, Amnon would be regarded by the people as a wicked fool, a God-rejecting man without principles who offended ordinary standards of morality, thereby jeopardizing Amnon’s right to the throne. the king … will not withhold me from you. Fourth, Tamar appealed to Amnon to fulfill his physical desire for her through marriage. She surely knew that such a marriage between half siblings was not allowed by the Mosaic law (Lev. 18:9, 11; 20:17; Deut. 27:22), but in the desperation of the moment, Tamar was seeking to escape the immediate situation.

Amnon manipulates the situation to get what he wants.

He lies

He abuses trust

He ignores Tamar’s clear warning

Tamar even appeals to reason and righteousness—but sin doesn’t listen.

Key Truth:

👉 When you choose sin, your heart becomes harder and less sensitive to what is right.

Illustration #2: Ignoring the Alarm

Imagine a fire alarm going off in your house—but instead of leaving, you unplug it because the noise bothers you.

👉 That’s what sin does. It ignores God’s warnings instead of responding to them.

Application:

When your conscience says “this is wrong”—listen

Don’t override conviction repeatedly

Respect boundaries—yours and others’

III. Sin Promotes Pleasure but Produces Agony - vs. 15-19

2 Samuel 13:15–19 NASB95

15 Then Amnon hated her with a very great hatred; for the hatred with which he hated her was greater than the love with which he had loved her. And Amnon said to her, “Get up, go away!” 16 But she said to him, “No, because this wrong in sending me away is greater than the other that you have done to me!” Yet he would not listen to her. 17 Then he called his young man who attended him and said, “Now throw this woman out of my presence, and lock the door behind her.” 18 Now she had on a long-sleeved garment; for in this manner the virgin daughters of the king dressed themselves in robes. Then his attendant took her out and locked the door behind her. 19 Tamar put ashes on her head and tore her long-sleeved garment which was on her; and she put her hand on her head and went away, crying aloud as she went.

After Amnon sins, the Bible says he hated Tamar.

His “love” turns into hatred

He discards her

The pleasure is gone—only damage remains

Key Truth:

👉 Sin always overpromises and underdelivers.

Illustration #3: The Empty Wrapper

Imagine being handed your favorite candy—but when you open it, it’s empty.

👉 Sin promises satisfaction, but it leaves you empty and ashamed.

Application:

Sin never gives what it promises

Lust is not love

What seems exciting now can leave lifelong consequences

IV. Sin Affects More Than Just You - vs. 20-33

2 Samuel 13:20–33 NASB95

20 Then Absalom her brother said to her, “Has Amnon your brother been with you? But now keep silent, my sister, he is your brother; do not take this matter to heart.” So Tamar remained and was desolate in her brother Absalom’s house. 21 Now when King David heard of all these matters, he was very angry. 22 But Absalom did not speak to Amnon either good or bad; for Absalom hated Amnon because he had violated his sister Tamar. 23 Now it came about after two full years that Absalom had sheepshearers in Baal-hazor, which is near Ephraim, and Absalom invited all the king’s sons. 24 Absalom came to the king and said, “Behold now, your servant has sheepshearers; please let the king and his servants go with your servant.” 25 But the king said to Absalom, “No, my son, we should not all go, for we will be burdensome to you.” Although he urged him, he would not go, but blessed him. 26 Then Absalom said, “If not, please let my brother Amnon go with us.” And the king said to him, “Why should he go with you?” 27 But when Absalom urged him, he let Amnon and all the king’s sons go with him. 28 Absalom commanded his servants, saying, “See now, when Amnon’s heart is merry with wine, and when I say to you, ‘Strike Amnon,’ then put him to death. Do not fear; have not I myself commanded you? Be courageous and be valiant.” 29 The servants of Absalom did to Amnon just as Absalom had commanded. Then all the king’s sons arose and each mounted his mule and fled. 30 Now it was while they were on the way that the report came to David, saying, “Absalom has struck down all the king’s sons, and not one of them is left.” 31 Then the king arose, tore his clothes and lay on the ground; and all his servants were standing by with clothes torn. 32 Jonadab, the son of Shimeah, David’s brother, responded, “Do not let my lord suppose they have put to death all the young men, the king’s sons, for Amnon alone is dead; because by the intent of Absalom this has been determined since the day that he violated his sister Tamar. 33 “Now therefore, do not let my lord the king take the report to heart, namely, ‘all the king’s sons are dead,’ for only Amnon is dead.”

The MacArthur Study Bible (Chapter 13) 13:20 do not take this thing to heart. Absalom told his sister not to pay undue attention or worry about the consequences of the rape. Absalom minimized the significance of what had taken place only for the moment, while already beginning to plot his revenge in using this crime as reason to do what he wanted to do anyway—remove Amnon from the line of succession to the throne (note also v. 32, where Jonadab knew of Absalom’s plans). desolate. She remained unmarried and childless. Her full brother was her natural protector and the children of polygamists lived by themselves in different family units.

This one act of sin destroys a family:

Tamar is devastated

Absalom becomes bitter and vengeful

David becomes passive

Eventually, Amnon is killed

Key Truth:

👉 Your sin will always impact others—even if you think it won’t.

Illustration #4: The Ripple Effect

Throw a rock into a pond. The ripple spreads far beyond where the rock landed.

👉 Sin is never isolated—it spreads pain to others.

Application:

Think beyond the moment

Your choices affect your family, friends, and future

Hidden sin still has visible consequences

V. Sin That Is Not Dealt With Leads to Massive Sin - vs. 28-39

2 Samuel 13:28–39 NASB95

28 Absalom commanded his servants, saying, “See now, when Amnon’s heart is merry with wine, and when I say to you, ‘Strike Amnon,’ then put him to death. Do not fear; have not I myself commanded you? Be courageous and be valiant.” 29 The servants of Absalom did to Amnon just as Absalom had commanded. Then all the king’s sons arose and each mounted his mule and fled. 30 Now it was while they were on the way that the report came to David, saying, “Absalom has struck down all the king’s sons, and not one of them is left.” 31 Then the king arose, tore his clothes and lay on the ground; and all his servants were standing by with clothes torn. 32 Jonadab, the son of Shimeah, David’s brother, responded, “Do not let my lord suppose they have put to death all the young men, the king’s sons, for Amnon alone is dead; because by the intent of Absalom this has been determined since the day that he violated his sister Tamar. 33 “Now therefore, do not let my lord the king take the report to heart, namely, ‘all the king’s sons are dead,’ for only Amnon is dead.” 34 Now Absalom had fled. And the young man who was the watchman raised his eyes and looked, and behold, many people were coming from the road behind him by the side of the mountain. 35 Jonadab said to the king, “Behold, the king’s sons have come; according to your servant’s word, so it happened.” 36 As soon as he had finished speaking, behold, the king’s sons came and lifted their voices and wept; and also the king and all his servants wept very bitterly. 37 Now Absalom fled and went to Talmai the son of Ammihud, the king of Geshur. And David mourned for his son every day. 38 So Absalom had fled and gone to Geshur, and was there three years. 39 The heart of King David longed to go out to Absalom; for he was comforted concerning Amnon, since he was dead.

Absalom doesn’t handle his anger biblically.

He holds bitterness for two years

He takes revenge

Violence increases the tragedy

Key Truth:

👉 Unresolved sin grows into bigger sin.

Illustration #5: The Untreated Wound

A small cut, if untreated, can become infected and dangerous.

👉 Bitterness and anger, if not dealt with, will grow into something destructive.

Application:

Deal with sin quickly

Forgive instead of holding grudges

Bring hurt and anger to God—not revenge

SO WHAT?

Conclusion: The Better Way

This chapter is dark—but it points us to truth:

👉 Sin destroys—but God restores 👉 Sin deceives—but God’s Word reveals truth 👉 Sin enslaves—but God offers freedom

Even in failure, there is hope through repentance and turning back to God.

Final Challenge for Teens

Ask yourself:

What thoughts am I allowing to grow?

Am I ignoring God’s warnings?

Is there sin I need to deal with today?

Am I holding onto bitterness?

👉 The best time to stop sin is early—before it takes control.
