“When he turned his back to leave Samuel, God gave him another heart” (v9). God called Saul to be Israel’s king, and the prophet Samuel anointed him (v1) as a sign of that call. Further, even though Saul had very little experience or reputation, God prepared him by giving him a new heart – a deep commitment – and pouring out His Spirit on him. Saul surprised everyone by prophesying (v10-11) just as the local prophets did. These signs confirmed God’s choice and helped people accept him.
“What has come over the son of Kish?” (v11). No matter our background, if God calls us to a task, he will also equip us and prepare us.
