Gal 6:4

6:4 test his own work. Paul urges the Galatian Christians to examine themselves as individuals before God, rather than drawing false confidence from relative comparisons with others (cf. 2 Cor. 13:5, 6).

reason to boast will be in himself. Lit. “have reason to boast in himself.” As Paul subsequently makes clear, reason for “boasting” is not to be found in one’s obedience to the law. While the Judaizers “boasted” of their success in encouraging legalism (v. 13), Paul “boasts” in the cross of Christ alone (v. 14; cf. 2 Cor. 11:16–12:10).
