Luke 6:37 Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven:
As a general rule we should avoid passing judgment on others because as we judge so we will be judged.
Matthew 7:2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
Romans 14:3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Romans 14:10 But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ...13 Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother’s way.
1 Corinthians 4:5 Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest
Having said that, there are occasions when we must judge.
John 7:24 Judge not according to the appearance, but judge righteous judgment.
Luke 12:57 Yea, and why even of yourselves judge ye not what is right?
1 Corinthians 5:9 I wrote unto you in an epistle not to company with fornicators: 10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. 11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. 12 For what have I to do to judge them also that are without? do not ye judge them that are within? 13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.
1 Corinthians 6:2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? 3 Know ye not that we shall judge angels? how much more things that pertain to this life? 4 If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church. 5 I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren? [In this case, "Judge" means to manage or administer, not to pronounce sentence upon. Angels do not sin but in God's kingdom on earth when Jesus returns they will be "ministering spirits" under the control of the saints.]
1 Corinthians 10:15 I speak as to wise men; judge ye what I say.
1 Corinthians 11:13 Judge in yourselves: is it comely that a woman pray unto God uncovered?
I hope you have found this helpful.
God bless you,
