[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].

including Paul, and Apollos, and Cephas [i.e., Peter], and the world, and life and death, and present and future things. All of these things are yours. [Note: Paul is showing that, as Christians, they really possessed and should value all preachers and circumstances of life alike].

So, we should observe the Festival [i.e., live the Christian life], but not with the old yeast [i.e., old sinful ways], such as the leavening [effect] of evil and wickedness, but with the unleavened bread of sincerity and truth.

But I wrote to you not to associate with anyone claiming to be a [Christian] brother who is [guilty of being] sexually immoral, or greedy, or an idolater, or who speaks abusively, or a drunkard, or a swindler. Do not even eat [a social meal] with such a person.

For what business is it of mine to judge outsiders? [i.e., non-Christians]; God judges them. But should you not judge those people who are inside? [i.e., Christians]. [So], remove the evil person from your fellowship [See Deut. 17:7].

If any one of you has a complaint against someone, how can you dare to take it before non-Christian judges [to be decided], instead of before the saints [i.e., God's holy people]?

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]?

I am saying this to make you ashamed. Can there not be found one wise person [there] among you who is able to decide [on a matter] between his [Christian] brothers?

But [instead], you yourselves do the wrong and cheat [others], and you do this to [Christian] brothers!

But the person who is joined to the Lord is one spirit [with Him]. [Note: Just as the person who has sex with someone enters a close physical union with that person, so the person who becomes a Christian enters a close spiritual union with Christ].

For the unbelieving husband is set apart [i.e., as an acceptable mate, although not yet saved. See verse 16], through his wife [i.e., her Christian commitment is viewed as having a godly effect on the home], and the unbelieving wife is set apart through the brother [i.e., for the same reason]. Otherwise, your children would be [considered] unclean. [Note: "Unclean" suggests they would be viewed as pagans were it not for one parent being a Christian]. But, as it is, they are set apart as acceptable [i.e., to God, because of the influence of the one Christian parent].

How can you know, [Christian] wife, whether or not you will [be able to] convert your husband? Or how can you know, [Christian] husband, whether or not you will [be able to] convert you wife?

Was any man already circumcised when he was called [by God to be a Christian]? Then he should not [try to] become uncircumcised. [Note: Some Jews in that day resorted to a surgical procedure in an attempt to conceal their circumcision]. Was any man uncircumcised when he was called? Then he should not become circumcised.

Brothers, each person should remain [in fellowship] with God in the [same] state he was in when he was called [by God to be a Christian].

And those who make use of the things of the world [should live] as though they were not [really] involved with them. For the world as we know it is passing away. [Note: The five "as though's" of verses 29-31 are intended to emphasize that Christians should live with eternity in mind and not to become preoccupied with even legitimate earthly circumstances].

A wife is bound [i.e., to stay married] for as long as her husband is alive. But if her husband dies, she is free to be married to anyone she wants; [but it must be] only in the Lord [i.e., he must be a faithful Christian].

Do we not have the right to take a believing [i.e., a Christian] wife with us [on our preaching tours], just like the rest of the apostles, and the Lord's brothers do [i.e., James, Joseph, Judas and Simon. Mark 6:3], and Cephas [i.e., Peter]?

This [i.e., the order of creation] is the reason that the woman should have [a symbol of] authority on her [physical] head [i.e., hair or a shawl to indicate subjection to her husband], and because of the angels. [Note: This difficult phrase probably means that angels, who observe the activities of Christian assemblies, are pleased when they see things being done in their proper order].

And there are a variety of [Christian] activities, but the same God provides the power for everyone to do all of them [i.e., it is God who empowers every person who has a gift].

So, if one part [i.e., one Christian] suffers, then all the parts [i.e., the other Christians] should suffer with it. Or, if one part is honored, all the [other] parts should rejoice with it.
