Paul began the third chapter of Philippians by expressing how there is no use for confidence in the flesh. In the previous verses, he listed his own accomplishments, but here he makes it clear just how little it matters.
See it for yourself in Philippians 3:7:
Paul’s language in this passage borrows language from the financial world, and he expresses things in terms of “profit” and “loss.” He will continue using this terminology in verse 8 as well.
What he has accomplished in life, which he recounted in verses 4-6, he now puts in the clearest light possible. What the world sees as an exquisite list of achievements, Paul places in the “loss” column.
It is interesting to note that Paul uses the plural form for the word “profit.” It is as if he takes his list of accomplishments and reviews them one by one, just as a miser hoards his pennies. Then Paul uses the singular form of the word “loss.” All of those achievements, Paul lumps together into one pile and casts it aside.
And he does not merely set it aside and forget about it, he views it as a liability, and regards it with disgust!
