First a little background. In the previous few chapters, King David's son Amnon fell in love with his half-sister Tamar, and when he couldn't seduce her, he raped her.
Tamar's full-brother Absolom was very angry with Amnon, but held it in for 2 years. Then he murdered him. Amnon was then afraid for his own life as a murderer, so he fled.
Now, two more years have passed...
Joab is a very wise person. He knows that Absolom belongs back in Jerusalem with his father, King David, in spite of his crime. But he knows David will never bring him back if Joab just suggests it. So Joab tells this wise woman how to act and what to say.
Look at verse 14, where he tells her to say, "But God does not take away life; instead, he devises ways so that a banished person may not remain estranged from him."
She could not have spoken a greater truth! And I'm sure neither she nor Joab knew just how prophetic that would be.
God has indeed devised a way that no banished person will remain estranged from him - if they choose to return.
See, Absolom didn't have to go back to Jerusalem. He could have stayed in Geshur, and lived out the rest of his days there, eaten up with guilt and shame. Or perhaps he was proud of what he did, and was still angry at his father for not defending Tamar's honor.
But the truth is that Absolom loved his father, and wanted to return. He wanted to see his father's face, and so he accepted the invitation, and returned.
Have you accepted God's invitation to return to Him?
