Note 13 at Phil. 1:10: The NIV translates this phrase as "you may be able to discern what is best." Paul is saying that increasing our understanding (see note 11 at v. 9) and application (see note 12 at v. 9) of God's love will cause us to have better discernment about right and wrong (see note 10 at Eph. 3:18, p. 1113).

Note 14 at Phil. 1:10: All of the things listed in verses 10-11 are the results of having our love abound through knowledge and judgment, which was mentioned in verse 9. We receive the love of God through faith at salvation. Then we increase our experience of God's love through knowledge and judgment. This leads to better discernment of what's right and wrong (see note 13 at this verse) and produces sincerity (pureness) which results in us walking without offense. If these things are working in us, then the fruits of righteousness follow, which causes glory and praise to God (v. 11).
