Saul died in battle as a direct result of his unfaithfulness, including consulting a medium (1 Chronicles 10:13–14). During a fierce battle where the Philistines had the upper hand, he was badly wounded by an archer (1 Samuel 31:3; 1 Chronicles 10:3). Because he considered is a humiliation and disgrace to be killed by the enemy, Saul asked his armor bearer to kill him (1 Samuel 31:4a; 1 Chronicles 10:4a). However, the armor bearer would not, so Saul fell on his sword, killing himself (1 Samuel 31:4b; 1 Chronicles 10:4b). So, the biblical account is that he died by suicide, and that is considered the more accurate one.
However, a young Amalekite, who apparently wanted to gain favor from David, who had been pursued for years by Saul, claimed that he killed Saul. He claimed that Saul asked him to kill him (2 Samuel 1:9), saying that he did as asked (2 Samuel 1:10a). It’s unclear whether the man specifically lied, taking credit for Saul’s suicide, or exaggerated his role from being present when Saul died. Regardless, David was not at all pleased that someone would kill whom God had anointed as king, and ordered the Amalekite be put to death (2 Samuel 1:14–16). In effect, the Amalekite hung himself by seeking glory at the expense of Saul.
If there’s one overarching lesson we can see from the life of Saul, it’s that sin leads to more sin, which leads to death. As the first king of Israel, Saul started well. However, he began disobeying God (1 Samuel 13:13–14; 1 Samuel 15:9). Because of this, God withdrew His favor and transferred it to David (1 Samuel 16:13–14). As God withdrew, Saul became more wicked and rebellious (1 Samuel 18:12ff), leading him to the occult (1 Samuel 28:7). His punishment was death (1 Chronicles 10:13–14).
David, too, sinned. He committed adultery (2 Samuel 11:4) and murder (2 Samuel 11:15). Because of this, he expressed fear that God would also abandon him (Psalm 51:11). However, the difference between these two men was not sin but their response. Saul continued to ignore his sin and make excuses for it. Conversely, David repented (2 Samuel 12:13) and expressed sorrow (Psalm 51:17).
Let us learn from this. No one is righteous (Romans 3:10), so God sent Jesus to be the only perfectly righteous human so that He could die in our place. However, Jesus’ death doesn’t mean that everyone is saved. Like David, we must recognize our sin and repent. We also have what David did not have: a once-for-all sacrifice (Hebrews 10:10). That means that, once we trust in Jesus, we are forever saved because our sin has been completely paid.
However, that doesn’t mean we keep sinning (cf. Romans 6:1). Instead, believers are to live a life of repentance. It’s not a repentance for salvation but for ongoing cleansing (1 John 1:9) so we can become like Jesus—living for what is good and reflecting Him to a world that desperately needs Him (1 John 3:3). Do not continue to harden your heart by ignoring your sin. Confess it. Jesus is more than willing to save all who come to Him (John 6:37)!
