After the first round of talks finished, each friends is going to go again - making the same arguments, only pressing harder and being more rude. Job has had enough of it "Miserable comforters are you all!".
When we're trying to comfort someone we shouldn't talk just for the sake of talking, we shouldn't sermonize and give pat answers, we shouldn't accuse or criticize. Instead, we should put ourselves in the other person's place and offer help and encouragement.
In 16:19ff we see Job appealing to a witness and advocate - sitting on this side of the NT we have the advantage of knowing that Jesus Christ is that advocate, interceding for us on our behalf.
In our 1 Corinthians passage this stood out to me...
9 Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality,10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God. 11 And such were some of you. But you were washed, you were sanctified,you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
Similar to his comments in Chapter 5, Paul is not expecting believers to be perfect. We still struggle with sin. But it no longer defines us, it no longer controls us. Those who persist in sin with no sign of remorse are not genuine Christians. As Christians, we need to be careful not to tolerate more "acceptable" forms of sin (greed, drunkenness, etc) while remaining outraged at others (homosexuality, adultery, murder, etc). We need to have high standards - Jesus sets the standard at perfection.
That being said, there are bigger consequences for some sins then for others. Sexual immorality is not only destructive to those involved in the sinful activity themselves. It has devastate countless lives, destroying families, churches, and communities. God's laws against sexual immorality (and all other sin for that matter) are for our own good.
When we become believers we no longer own our bodies. They were bought at a price. Christ's death frees us from sin, but we are now His, and because our body belongs to God we need to use it for His glory and not violate His standards for living.
