The tone... the tone... Mitchell gave wise advice but since he has criticized me before it went on deaf ears. JonC has not. Why is this so hard for you to understand?
Unfortunately, criticism does not always come across in a tone we would prefer. However, the important thing is not the tone but the correctness of the criticism. The critic will have to answer to God for their tone, but what you will have to answer to God for is the truth of the criticism. Are they telling you the truth? If they are, don't try to justify disobedience to the truth simply because the tone offends you. Try to get yourself out of the way and then consider the criticisms objectively asking yourself are they telling me what it true? The great thing about being wrong and knowing you are wrong, is that now you are in a better condition to seek what is right and be right.
