Galatians 6:3-4

Amplified Bible

³ For if anyone thinks he is something [special] when [in fact] he is nothing [special except in his own eyes], he deceives himself. ⁴ But each one must carefully scrutinize his own work [examining his actions, attitudes, and behavior], and then he can have the personal satisfaction and inner joy of doing something commendable ^[a]without comparing himself to another.
