My dogs often bark in the middle of the night to let me know that something is going on.
There are Christians that are the same way. They feel it is their job to be the watchdogs and point out every problem. Unfortunately, watchdogs are focused outward and miss what is inward.
“Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.” Mathew 7:3-5
