(CLV) Mt 7:1
"Do not judge, lest you may be judged,
So many read that verse and stop short; to say that we should exercise judgement, concerning the wicked. That we should just turn a blind eye to wickedness and go off into a day dream singing, "la la la - la la." "I have no responsibility to see the world for what it is." "There is no wrong; there is no right in my eyes. It's all on the Father's hands"
The very next verse:
(CLV) Mt 7:2
for with what judgment you are judging, shall you be judged, and with what measure you are measuring, shall it be measured to you.
YHWH calls us to righteous judgement. This falls in line with what is mentioned just a few verses later:
(CLV) Mt 7:12
All, then, whatever you should be wanting that men should be doing to you, thus you, also, be doing to them, for this is the law and the prophets.
Yahshua doesn't contradict himself.
(CLV) Jn 7:24
Be not judging by the countenance, but be judging just judging."
Again he tells us to judge justly.
(CLV) 1Co 6:3
Are you not aware that we shall be judging messengers, not to mention life's affairs?
Let me quote where Jesus told someone they judged rightly:
Luke7v36to50
Now one of the Pharisees invited Jesus to have dinner with him, so he went to the Pharisee's house and reclined at the table. When a woman who had lived a sinful life in that town learned that Jesus was eating at the Pharisee's house, she brought an alabaster jar of perfume, and as she stood behind him at his feet weeping, she began to wet his feet with her tears. Then she wiped them with her hair, kissed them and poured perfume on them.
When the Pharisee who had invited him saw this, he said to himself, "If this man were a prophet, he would know who is touching him and what kind of woman she is - that she is a sinner."
Jesus anwered him, "Simon, I have something to tell you."
"Tell me, teacher," he said.
"Two men owed money to a certain money-lender. One owed him five hundred denarii, and the other fifty. Neither of them had the money to pay him back, so he cancelled the debts of both. Now which of them will love him more?"
Simon replied, "I suppose the one who had the bigger debt cancelled."
"You have judged correctly," Jesus said.
Then he turned towards the woman and said to Simon, "Do you see this woman? I came into your house. You did not give me any water for my feet, but she wet my feet with her tears and wiped them with her hair. You did not give me a kiss, but this woman from the time I entered, has not stopped kissing my feet. You did not put oil on my head, but she has poured perfume on my feet. Therefore, I tell you, her many sins have been forgiven - for she loved much. But he who has been forgiven little loves little."
Then Jesus said to her, "Your sins are forgiven."
The other guests began to say among themselves, "Who is this who even forgives sins?"
Jesus said to the woman, "Your faith has saved you; go in peace."
How did Simon judge rightly? Not by judging Jesus for allowing a sinner to come to him, nor judging the woman.
He judged rightly in admitting he showed less love for Christ than the woman did, that the woman honored Jesus more than he did himself.
It's interesting that you don't finish the "judge not" passage, which says if you have a 2x4 in your own eye, how can you judge the person with a piece of sawdust. Hypocrite!
First, remove the 2x4 from your own eye, then help your neighbor remove the sawdust from theirs.
So often, I have had a Christian say, "I can judge a person doing x when I am not doing x myself, so, not a hypocrite.
If that were true, Christ would have said to remove the 2x4 from your eye to remove the 2x4 from your neighbor.
A 2x4 would block your vision. It would poke out your neighbor's eye when trying to remove the sawdust.
What is said is to remove something significant from your eye to help your neighbor with something minor.
One of the major problems the Pharisees had was using the law to burden people, rather than guide them, with laws such as the number of steps one can take on the Sabbath. Yet, they didn't follow these same rules themselves. They did this because the enjoyed the power if authority, had access to Scriptures and could read, so their interpretation was thought to be the Word of God. They were thought to be holy by the people.
They lacked love. They lacked mercy, and humility. They not only judged those who Christ ate with, they wouldn't even acknowledge them, thinking God couldn't possibly love sinners, and Christ, in eating with them, honored them, showed them that they were loved now, as they were. This is what changed so many people who encountered Christ.
If you judge with harshness, you will be judged harshly. If you judge from a legal standpoint, so shall you be held to the entire law.
Christ was not harsh with the sinners.
He was harshest with the Pharisees, over confident in their holiness. He chastised them for knowing how much dill and thyme to tithe, but not mercy, love and forgiveness.
And so you present a false dichotomy:
A) Judge someone for their sin
B) Ignore any sin or injustice all together
Those aren't the only choices.
Before I point out the sin of another, I look at myself first. What is my motivation? Do I want to feel superior? Do I want to point out their sin to pull focus from mine? Do I want to be right?
Am I really doing it to help them, for their benefit? Or do I want them to obey me, and agree with my position?
Then I pray about it, seeking the spirit for advice.
NonChristians often see Christians as being judgemental:
"I'm here to talk to all you drunkards. I'm here to talk to all you fornicatirs. I'm here to talk to all you herma-sexshals. Repent...from yer wicked ways-ah! Or you will burn..."
U of Mn crowd: The Lake of Fire!!!!wooooo"
Brother Jed and Sister Cindy judged all of these people, but never really sat down with anyone, and met them. They preached ridiculously, and students treated like Rocky Horror Picture Show, the students reinforcing how religion is just crazy, and Brother Jed and Sister Cindy, often laughed at, able to convince themselves the world is evil.
Christ didn't walk through town, pointing and calling people's sin, and condemning them or demanding repentance. He healed the sick, as he said. He allowed them to understand that they were loved by the Father. He built then up.
So in my life, I look at my own weaknesses, and pray to change my life, the only one I can control.
I allow others the right to have free will and make their own choices. Should I need to point out a friend's drinking problem, for example, I do it in support, and then let it go.
However, if I see someone harming others, discriminating against others, or see social injustice, I fight against it by drawing attention to it.
Why would anyone waste the majority of their time just judging others? For what purpose?
