"I don't judge," a person may say. Well, it is good that one doesn't, because the word of God teaches men not to judge. Matt 7:1-2. Rom 14:10. Judging is a person giving their own opinion about a matter and passing those thoughts off as the law of the land. On the other hand, a person reading something which the word of God teaches and showing an offender where he is wrong; is not judging. Instead that is correction by the word of God. 2 Tim 3:14-17. Heb 4:12-13.
For example, one is not judging by showing a thief that the word of God condemns stealing. Eph 4:28. Nor is one judging a gay person by showing that the scripture condemns homosexuality. Rom 1:26-32. So, it is not correction by the person who showed the scripture to the offender; but rather the scripture showing the offender where he is in error.
So remember, a person giving his personal thoughts as law, is judging. But showing one what the Bible teaches is correction with the truth, the whole truth and nothing but the truth. Let that truth set you free. John 8:31-32.
