What does Philippians 1:10 mean?

A growing love helps us "approve what is excellent." Paul also used the Greek word diapheronta, translated "excellent," in Romans 2:18.In 1 Corinthians 12:31, setting up 1 Corinthians 13, love is the "more excellent way." In Titus 3:8, Paul's teachings were as described excellent and profitable for all people.

Those who grow in love will be morally pure. Paul will again mention purity in Philippians 4:8, adding, "Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things." Paul also notes his goal for the Philippian believers to be "blameless" in Philippians 2:15. He considered himself "blameless" in the eyes of law, though it was only Christ who could make him blameless before the Lord (Philippians 3:6).

Similarly to verse 6, verse 10 refers to the "day of Christ." This may be a reference to the rapture, or to the beginning of the millennial kingdom. More likely, it is a general allusion to the hopeful future awaiting all true believers.
