[Isa. 40:13 says], "For who knows [what is in] the Lord's mind? And who is capable of instructing Him? But we have the mind of Christ. [Note: The "we" may refer to the apostles, who had the gift of inspiration (See verse 12), or to all Christians who have spiritual discernment].

Or, do you not know that God's people will judge the world? [Note: Possibly this refers to Christians somehow assisting Christ on the judgment day]. And if the world is [to be] judged by you [at that time], are you not capable of judging small matters [now]?
