What does 2 Corinthians 4:15 mean?
Paul reminds the Christians in Corinth again of one of his primary motivations for continuing to endure so much suffering. He tolerates great hardship in order to shine the light of Christ to more and more people. In short, he does it for their sake and, presumably, for the sake of others like them.Some in Corinth may have questioned why Paul suffered so much if he was truly an apostle of Jesus and a servant of God. Shouldn't God prevent his trusted servant from experiencing so much pain? Paul's reply has been that God does not spare his servants from suffering, but that God provides for them through their suffering. More, God will raise them from the dead if their suffering should lead to that. Despite what many people think, faithfulness to God does not protect a person from all earthly difficulty.
Now Paul declares that this service to the Corinthians is worth it, in part, because as more people believe in Jesus, more people will receive God's grace. The more people who receive God's grace, the more people who will give thanks to God. More and more glory will be brought to God. Paul is willing to endure anything, enabled by God's power, to achieve this outcome.
