This is a textual lesson from Paul’s first letter to the church in Corinth. Paul is correcting some false perceptions about being spiritual and also some false views about God’s servants, specifically those that had been working among the church in Corinth (Paul, Apollos, etc). The church needed to be reminded that spiritual people must also act spiritual (not with rivalries and contentions). They also needed to be reminded that their teachers were just servants of God and not to be praised. Using a farming analogy, Paul points out that God owns the land, the workers, and the crop that is produced.
This is a textual lesson from 1 Corinthians 2. I wasn’t sure whether to call it spiritual discernment or spiritual revelation. Perhaps Paul’s point is that spiritual people will accept the revelation from God through the Holy Spirit. To the natural man, spiritual revelation seems foolish so he relies on worldly wisdom.
