Crispus, the leader of the synagogue, and all of his family became believers in the Lord. [And] many of the Corinthians who heard [Paul's message] believed [in the Lord] and were immersed [into Christ].

Using the unearned favor shown to me by God [Note: Paul here probably refers to his apostleship and its attending spiritual gifts], as an expert building contractor, I laid the foundation [i.e., in starting the Corinthian church], and someone else is building on it [i.e., Apollos. See verse 6].

I now want to reply to the matter of idolatrous sacrifices [which you wrote to me about]. We know that we all possess knowledge. [Note: This may be a statement posed to Paul by the Corinthians, who seemed quite preoccupied with "knowledge"]. Knowledge [only] makes people arrogant, while love builds them up [spiritually].

For the person who speaks in a language [supernaturally] does not speak to people, but to God, for no one can understand him [i.e., unless there is an interpreter or it is the person's native language]; he speaks [previously] unrevealed truths under the influence of the Holy Spirit [or "in his spirit"]. [Note: For a correct understanding of this chapter, it must be kept in mind that Paul is addressing a misuse ofthe gift of speaking in languages supernaturally. The Corinthians were doing this in the wrong way and for the wrong purpose].

For they cheered me up, as they have cheered [or, will cheer] you up [also]. [Note: How these three men did this for Paul and the Corinthians is not known]. You should give recognition to such men.

We have spoken freely to you, O Corinthians, and our hearts have been wide open to you.

For even though I caused you sorrow by my letter [Note: Paul's writing of I Corinthians to correct abuses at Corinth apparently produced sorrow for their wrongdoing], I do not regret it, though I did regret it. [For] I see that my letter hurt you, though only for a short time.

And we have sent [i.e., are sending] with them our brother [Note: This is a different person from the one mentioned in verse 18], who has often proven his diligence to us in many ways, and is now proving to be even more diligent because of the great confidence he has in you [i.e., confidence in the Corinthians completing their collection for the poor].

Now I Paul, who am humble [when speaking] face to face with you, but bold when I am away from you, urge you by the meekness and gentleness of Christ [Note: This means either Paul was imitating Christ's behavior or that the Corinthians were to do so]:

[And we are] prepared to punish all disobedience when your obedience is complete. [Note: This probably refers to the Corinthian church dealing with its unrepentant member. See I Cor. 5:3-5].
