Judge not

Romans  14:13A ...Therefore, let us stop passing judgement on on another

Matthew 7:1 Judge not lest you be judged

6 reasons no to Judge... Roman 2:1-5 ( from Beth Moore study)
                                                          ( Living beyond yourself)

1- When we judge others, we invite the discipline of our Heavenly father
2-We do most of the same things that we condemn in others
3-We do not know the whole truth
4-We are mere humans
5-When we judge others. we are judging God
6-God's judgement is always righteous. Our is tainted by the flesh

There are many more reasons, but that is a good start
