Phil. 4:13 is one of the most misinterpreted verses in the Bible and one of the most misapplied verses. It is often used to say that one can pass a hard test having not studied. Some use it to say they can accomplish a seemingly impossible athletic task. Some use it to say that they can accomplish any other task that seems impossible. They can do it because Christ strengthens them. Is this what this verse teaches?
Context: Paul was thanking the church at Philippi for financial assistance in his ministry. Paul is speaking of the fact that he had learned to be content in whatever state he was in. He had learned to be content whether he was abased or abounding, whether full or hungry, and whether abounding or in need.
Summary: Paul is basically saying that contentment is better than riches. He could do all things and be content in whatever state he was in, as long as it was God's will.
The Greek Work for content means "Sufficient, satisfied, or adequate." Whatever God's will was for his life, he was content in it.
The best state to live in is the state of contentment!
Let the Scripture speak!
