Judge not – you have no excuse.

Romans 2:1

1 Therefore you have no excuse, O man, every one of you who judges. For in passing judgment on another you condemn yourself, because you, the judge, practice the very same things.
2 We know that the judgment of God rightly falls on those who practice such things. – Romans 2:1-2

The Lord said:

1 “Judge not, that you be not judged.
2 For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you.
3 Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye?
4 Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye?
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. – Matthew 7:1-5

The log in our own eye is the weight of our own personal sin before God. That weighs heavily on our soul, a great burden that is lifted from us by the Lord.

2 Bear one another’s burdens, and so fulfill the law of Christ.
3 For if anyone thinks he is something, when he is nothing, he deceives himself.
4 But let each one test his own work, and then his reason to boast will be in himself alone and not in his neighbor.
5 For each will have to bear his own load. – Galatians 6:2-5

One of the greatest way to bear another persons burden and help alleviate the weight on their shoulders is to pray with them. Then if the Lord shows you a practical way to help, do it in love not expecting anything in return.

13 Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing praise.
14 Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord.
15 And the prayer of faith will save the one who is sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. – James 5:13-15

We should get down and dirty with someone, acting as the Good Samaritan did (Luke 10:33-35), treating his woulds, transporting him to help and paying for his care. Not judging them but identifying with them. If you judge someone the very thing you judge them for will be the thing you get judged for (Matthew 7:2). The spiritual principle that we reap what we sow (Galatians 6:7, Job 4:8). God is the righteous judge had He alone has the right to judge us, His ways are fair and we should be fair with others:

Masters, treat your bondservants justly and fairly, knowing that you also have a Master in heaven. – Colossians 4:1

What does the Lord require?

Thus says the LORD: “Keep justice, and do righteousness, for soon my salvation will come, and my righteousness be revealed. – Isaiah 56:1

He has told you, O man, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God? – Micah 6:8
