<p>3:21 <i>Therefore, let no one boast in men. For all things are yours</i>- The boasting in men may refer to boasting in human teachers and their words of human wisdom. But these &quot;men&quot; are defined in :22 as Paul, Apollos and Peter. In chapter 1, Paul laments how the church has split into factions around these men. So he is here repeating the basic point made there- the cross of Christ is the fundamental basis of faith. Anything else added to it is mere human thinking. To start talking about perceived differences between those three Christian leaders was just the same as worldly wisdom. And surely none of those three men in themselves approved of the divisions being made around them. The &quot;all things&quot; in view are those of 1 Cor. 1:5; the gift of the Spirit had given them &quot;all things&quot; in the Spiritual sphere. Again the appeal is to realize what they have potentially been given by the gift of the Spirit. To start talking about the superiority of Paul's teaching over Peter's was a sign that they failed to be awed as they should by the &quot;all things&quot; given them in Christ. The spirit of Christ gave them the &quot;all things, yes, the deep things of God&quot; (1 Cor. 2:10). Through the Spirit, God was working all things in all men in the church (1 Cor. 12:6) and will articulate this 'all things in all men' at the final change to immortality (1 Cor. 15:28). </p>
