Verse and question study
Does "do not be unequally yoked" forbid a Christian from marrying an unbeliever?
Many readers apply it to marriage, and the principle certainly extends there: Paul elsewhere says a widow may marry "only in the Lord" (1 Corinthians 7:39). But in context the passage addresses a wider range of binding relationships, particularly religious and idolatrous ones. It should not be used to tell a believer who is already married to an unbeliever to leave the marriage, since Paul teaches the opposite in 1 Corinthians 7:12–16.
Does this mean Christians should withdraw from non-Christians?
No. Jesus mixed with sinners, and Paul tells the Corinthians that they cannot leave the world (1 Corinthians 5:10). Believers are to be salt and light, in the world but not of it. Separation concerns compromise of faith and conduct, not contact.
Can a person receive God's grace "in vain"?
Paul's warning is directed at a church, which includes true and false professors. Grace received in vain refers to a response that does not become faith and fruit. This is consistent with the truth that those whom God has truly saved will persevere, and that perseverance is the proof of genuine faith.
What is the significance of the promise "I will be a father to you"?
It shows that the Christian's relationship with God is not that of a servant to a distant master but of a child with a Father. The promise made to David's offspring is extended to all who are in Christ, men and women alike, and this adoption (Romans 8:15; Galatians 4:4–7) is a central blessing of the gospel.

Historical and literary context
Chapter 6 continues the long defense of Paul's ministry (2:14–7:4). The first verses finish the appeal begun in 5:20, and the middle section is a famous catalog of the sufferings and the virtues that mark a true minister of Christ. The appeal in verses 11–13 is deeply personal and prepares for 7:2–4, and the passage between (6:14–7:1) has long puzzled interpreters because it seems to interrupt the flow. Some have suggested that it is a fragment from another letter, but there is no manuscript support for that view, and the passage connects naturally with the surrounding material: Paul asks the Corinthians to open their hearts to him and close them to the false teachers and idolatrous practices that were competing for their loyalty. The Corinthians lived in a city where participation in temple feasts, trade guilds, and civic religion was socially expected, so the call to separation was practical and costly.

Apologetic note
Paul's catalog of hardships and his call to separation had practical effects that outsiders noticed. Early Christians refused to participate in the sacrifices and festivals that were woven into civic life, and this made them seem odd and sometimes dangerous. Pliny the Younger, governor of Bithynia, wrote to the emperor Trajan around AD 112 about the Christians in his province. He found that they gathered before dawn, sang to Christ "as to a god," and bound themselves by oath not to commit theft, fraud, or adultery. His investigation turned up no crimes, only what he called a stubborn and excessive superstition. This independent, hostile source confirms that the Christian community of the early second century was marked by moral seriousness and a refusal to compromise its worship. The paradoxes of verses 8–10 also describe the Christian condition in the Roman world: regarded as impostors, dying yet living, poor yet enriching others.
