1 Corinthians 6
Being wise and humble in God's knowledge.
V2: "Do you not know that the saints will judge the world? And if you are to judge the world, are you not competent to judge trivial cases?"
V3: "Do you not know that we will judge angels? How much more the things of this life!"
We have the authority in God's kingdom. Ultimately, being humble towards one another.
V12: "'Everything is permissible for me"—but not everything is beneficial. "Everything is permissible for me'—but I will not be mastered by anything."
This chapter is pretty self explanatory, I think.
