What is the context?
This passage follows Paul’s restrained account of revelations from the Lord. The first words continue his explanation of why he avoids being credited too highly. He then describes a thorn that keeps him from conceit, calling it a messenger of Satan that torments him.
He pleads with the Lord three times for it to be taken away. The account records the Lord’s response about sufficient grace and power perfected in weakness.
Paul responds by welcoming Christ’s power resting on him in his weakness. The fuller paragraph, 2 Corinthians 12:7–10, places that response among the hardships he endures for Christ.
How is this passage commonly understood?
Christians commonly read this as Christ sustaining Paul when the thorn remains. Wesley’s notes on verses 8–9 and the USCCB notes on verses 8–9 connect the repeated prayer with the answer of sufficient grace. The exact identity of the thorn remains uncertain.
Where does this fit in God's plan?
2 Corinthians 4:7–12 describes the life of Jesus being revealed through His vulnerable servants. Their weakness makes clear that the power comes from God, and their costly ministry brings life to others.
That wider setting helps explain why Paul values Christ’s power resting on him. God’s work through him continues amid weakness, serving people through the gospel. The grace described here sustains him in that calling.
What is our position?
Our study What Does Prayer Look Like?, in its section on Paul’s thorn, understands this as an answer that supplies grace while the suffering remains. Its position is that hardship does not prove God is absent or inattentive. We can trust His care even when the answer takes a different form from the relief we asked for.
