1 Corinthians 6:5-7

6:5 I say this to your shame! Is there no one among you wise enough to settle disputes between fellow Christians? 6:6 Instead, does a Christian sue a Christian, and do this before unbelievers? 6:7 The fact that you have lawsuits among yourselves demonstrates that you have already been defeated. Why not rather be wronged? Why not rather be cheated?

1 Corinthians 6:15-18

6:15 Do you not know that your bodies are members of Christ? Should I take the members of Christ and make them members of a prostitute? Never! 6:16 Or do you not know that anyone who is united with a prostitute is one body with her? For it is said, “The two will become one flesh.” 6:17 But the one united with the Lord is one spirit with him. 6:18 Flee sexual immorality! “Every sin a person commits is outside of the body” – but the immoral person sins against his own body.
