고린도후서

2 Corinthians was written by the apostle Paul around 55-56 AD from Macedonia. It is Paul's most personal and emotionally intense letter, written after a painful visit to Corinth and a severe letter (now lost). Titus brought the good news that the Corinthians had largely repented, prompting this response of relief, defense, and encouragement.

2 Corinthians contains 13 chapters: Paul's comfort in affliction and defense of his ministry (chapters 1-7), instructions about the collection for Jerusalem's poor (chapters 8-9), and Paul's vigorous defense of his apostolic authority against false teachers (chapters 10-13).

The main theme of 2 Corinthians is strength in weakness. Paul defends his ministry by embracing vulnerability: 'My grace is sufficient for you, for my power is made perfect in weakness' (12:9). The book reveals that authentic Christian ministry is characterized not by outward power but by suffering, transparency, and dependence on God.

Key teachings include: comfort in affliction — 'the God of all comfort' (1:3-4), the new covenant ministry surpassing the old (chapter 3), 'we have this treasure in jars of clay' (4:7), being 'away from the body and at home with the Lord' (5:8), the ministry of reconciliation (5:18-21), generous giving (chapters 8-9), Paul's thorn in the flesh (12:7-10), and the criterion of authentic apostleship (12:12).

2 Corinthians provides the most intimate window into Paul's personal struggles and theology of suffering. The passage 'God made him who had no sin to be sin for us, so that in him we might become the righteousness of God' (5:21) is one of the clearest statements of substitutionary atonement. The book's teaching on weakness as the context for divine power has shaped Christian understanding of leadership and ministry.
