It really bothers me when people, say you shouldn’t judge and then point to Matthew 7
“Judge not, that you be not judged. For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you. Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye? Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye”
Most stop reading there to put Jesus in their corner. Who better to use than Jesus right? You have to keep reading the rest of the passage to pick up the full meaning of what Jesus was trying to communicate.
“You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother’s eye. Do not give dogs what is holy, and do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you.”
Jesus calls us to judge righteously, not hypocritically. Of course this is really only meant for Christians. The last part of that verse makes it clear, judging someone who has no clue (or doesn’t care), is useless.
