Leviticus 19:17
The warning of Leviticus 19:17, “...thou shalt surely rebuke thy neighbor, and not allow sin upon him,” is preceded by warnings against spreading slander and nursing inner hatred You can easily determine, therefore, when you should criticize and when you shouldn’t by asking yourself these three questions:
(1) Am I motivated by an earnest desire for the welfare of the person I think needs correcting?
(2) Am I going to face him honestly, but gently?
(3) Do I find the task thoroughly disagreeable, or am I secretly getting some pleasure out of it?
