1 Corinthians 5
9 I wrote to you in my epistle not to keep company with sexually immoral people. 10 Yet I certainly did not mean with the sexually immoral people of this world, or with the covetous, or extortioners, or idolaters, since then you would need to go out of the world. 11 But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner—not even to eat with such a person. 12 For what have I to do with judging those also who are outside? Do you not judge those who are inside? 13 But those who are outside God judges. Therefore “put away from yourselves the evil person."
As a brother and elder I'm required to bring correction to my brothers or sisters who are giving themselves over to sin, and disassociate with them if they persist unrepentant.
As a witness I'm required to accurately identify sin before the lost in the context of pointing them to the redemption offered by the blood of Jesus, acknowledging that apart from grace I am every bit as much a sinner.
I have no requirement from my Lord to transform society or its institutions.
Does the Holy Spirit play a role in convicting Christians or unbelievers of sin? Or can you do it according to your own understanding without any help from God?
