Mark Dever‘s “The Five Points of Criticism” is insightful and wise.
The five points:
- “Directly, not indirectly”
- “Seriously, not humorously”
- “As if it’s important, not casually”
- “Privately, not publicly”
- “Out of love for them, not to express your feeling or frustration”
Update: Jonathan Leeman adds a sixth point: ending with a word of encouragement.
