The word "now" emphasizes how Paul has changed since he quit being a Pharisee and became a believer in Christ. AT: "now that I have trusted in Christ, I count" (See: [[rc://en/ta/man/translate/figs-explicit]])
Paul is continuing the business metaphor from [Philippians 3:7](./07.md), saying it is worthless to trust in anything other than Christ. AT: "I consider everything to be worthless" (See: [[rc://en/ta/man/translate/figs-metaphor]])
