The Book of Philippians is called an epistle, a letter to the Christians living in the city of Philippi. When Paul wrote this letter, he was in prison. Biblical studies approximate that he'd been in prison for 2 years, and Paul wasn't sure if he's going to be released or if he's going to die. Let's look at what he wrote.
"Not that I was ever in need, for I have learned how to be content with whatever I have. I know how to live on almost nothing or with everything. I have learned the secret of living in every situation, whether it is with a full stomach or empty, with plenty or little. For I can do everything through Christ, who gives me strength" (Philippians 4:11-13, NLT).
Can you imagine being in Paul's situation? He's unsure of the future, and didn't know whether he was going to live or die. But he continues to live in faith. He knows the secret of living, no matter what life throws his way. And that secret is Jesus Christ, because Jesus gives us the strength to keep going.
Doing everything doesn't mean doing everything. It doesn't mean being supermom or dad or superkid. It means living contently with what you've got, and getting through what's going on by the strength of Jesus. Whether you've hit rock bottom in prison or you're having problems at school or work or home, Jesus can give you the strength to get through it all. What's the secret of living? Jesus.
