This chapter instructs us in temporal matters, lawsuits, and in the latter part, fornication.
It is contrary to Scripture for a believer to go to law against another believer rather than before the assembly.
Since the time is coming when the saints will judge the world, even angels, cannot the saints judge these matters? There should be a wise man in the assembly able to settle the matter between the saints before the assembly. Why not suffer the wrong and leave it with the Lord?
Those who will not inherit the kingdom of God are listed, and it is good for us to remember that we were such before we were saved. How much guilt has been washed away in the blood of Christ! We are justified, but we need grace not to be brought under the power of evil.
The apostle added another warning against fornication. Our bodies are the temple of the Holy Spirit, a solemn consideration to know that God the Spirit dwells in us, hence, being bought with a price, we should glorify God in our bodies which are God's.
