Yes but we really are our Brother's keeper and we need to hold one another accountable for sin. There are plenty of scriptures for that too. Judgement starts at the House of God.

Food for thought thanks :D - if we get so wrapped up in other peoples business, then we lose focus on what work we need to do.  I guess if we get our own 'buisness' dealt with, we'll have the strength to help others when they need.  We can't walk each others paths, but we can walk alongside each other as we walk our own.

@xXrEMmUsXx@xanga - 
1 Peter 4:17 implies that yes we are supposed to keep each other accountable for sin like I said, and in Genesis 4:9 God asked Cain "Where is your Brother?" Cain replied "Am I my Brother's keeper?" God was mad because Cain slew able. The implication is that yes, he indeed was his brother's keeper. The Household of God, refers to the Household of Faith, or our Brothers and Sisters in Christ.

@xXrEMmUsXx@xanga -  What about Matthew 18:15-16? Or Leviticus 19:17?  Galatians 6:1? 2 Thessalonians 3:15? Titus 3:10? Or James 5:19?

Matthew 18:

He touched her hand, and the fever left her; and she got up and

waited on Him.

When evening came, they brought to Him many who were demon-possessed; and He cast out the spirits with a word, and healed all who were ill.

Leviticus 19:

15 “Do
not twist justice in legal matters by favoring the poor or being
partial to the rich and powerful. Always judge people fairly.

16 “Do not spread slanderous gossip among your people.[b]

“Do not stand idly by when your neighbor’s life is threatened. I am the Lord.

17 “Do not nurse hatred in your heart for any of your relatives.[c] Confront people directly so you will not be held guilty for their sin.

18 “Do not seek revenge or bear a grudge against a fellow Israelite, but love your neighbor as yourself. I am the Lord.

19 “You must obey all my decrees.

“Do
not mate two different kinds of animals. Do not plant your field with
two different kinds of seed. Do not wear clothing woven from two
different kinds of thread.

Of course there are different translations... But in verse 15, it says to judge people fairly. I think the point here is that - people will sin. We will have to confront sin and we are not to mingle with that sin. Discerning right and wrong are very different than placing actual judgement for a sin with consequences on another believer. (without going into the whole Old Law and New Testament law being written on our Hearts... in short - there were 613 Jewish laws, and aside from the temple laws, they are still help by the Jewish people. So when the Old Testiment Commands something, thought it be moral, I ask myself what Jesus taught and where He was going with his teachings to renew the mind and set people free and He said - Do not Judge. Matthew 7 [since this is concerning sin})

Galatians 6:1 Dear brothers and sisters, if another believer[a] is overcome by some sin, you who are godly[b]
should gently and humbly help that person back onto the right path. And
be careful not to fall into the same temptation yourself.

While helping someone out of sin does require discernment, judgements of their character and condemnation will not prepare their hearts for repentance.

2 Thes 3:15 15 Don’t think of them as enemies, but warn them as you would a brother or sister.[e]

Titus 3:

Do not get involved in foolish discussions about spiritual pedigrees

or in quarrels and fights about obedience to Jewish laws. These things are useless and a waste of time.

If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them.

For people like that have turned away from the truth, and their own sins condemn them.

My dear brothers and sisters, if someone among you wanders away from the truth and is brought back,

you
can be sure that whoever brings the sinner back will save that person
from death and bring about the forgiveness of many sins.
