Did you know that judgeing others is a sin?
No, what I know is that hypocritical judgment without mercy is a sin and that only the Lord can judge the hearts of people.
Matthew 7:5 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.
1 Corinthians 5:9 I wrote to you in my letter not to associate with sexually immoral people-- 10 not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world.
11 But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler--not even to eat with such a one. 12 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? 13 God judges those outside. "Purge the evil person from among you."
6:1 When one of you has a grievance against another, does he dare go to law before the unrighteous instead of the saints? 2 Or do you not know that the saints will judge the world? And if the world is to be judged by you, are you incompetent to try trivial cases? 3 Do you not know that we are to judge angels? How much more, then, matters pertaining to this life!
