Galatians 6:3-5

3For if anyone thinks he is something [special] when [in fact] he is nothing [special except in his own eyes], he deceives himself.

4But 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 without comparing himself to another.

5For every person will have to bear [with patience] his own burden [of faults and shortcomings for which he alone is responsible].
