And standing over her, He rebuked the fever, and it left her; and she arose and waited on them. (Luke 4:39 NASB)
She arose. Anestemi. The Greek word translated "arose", anestemi, (blueletterbible.org) can also be translated "got up". The interesting thing is that it is also the same word used to indicated "rise from the dead ".
The way I see this verse, Peter's mother-in-law had intended to entertain Jesus as well as her son-in-law and whoever they brought along. A terrible fever left her prostrate in the bed, unable to serve. It stopped her in her tracks and no ministry was possible until this illness was resolved. In a way, she was dead to service (and very nearly dead and in the grave). When Jesus came, He rebuked the fever, it left, and she arose, just as one who rises from the grave. He restored her physical health, but He also restored her life of service.
There is no indication at all that she had a sin sickness. She had a physical fever. The "fever" of sin can, however, stop us in our tracks and end all service to the Kingdom of God. I've been there, and you may have been, too. With a word (Forgiven), Jesus can enter our situation, bring healing, and restoration. We can be useful in the Kingdom of God again, and so can our loved ones. They can be faithful servants of the Most High God, regardless of how unlikely that seems today.
Today, pray that Christ will intervene in our hearts and in the hearts of our loved ones, bringing healing and restoration of service in the way only He can accomplish.
