Moreover, Paul had a “thorn in the flesh”​—possibly an affliction of the eyes.​—2 Corinthians 12:7; Acts 23:1-5; Galatians 4:15; 6:11.

Like Paul, many of us have some affliction. But this makes us more dependent on God’s strength, and in our weakness his power is made especially manifest among those to whom we preach.​—2 Corinthians 12:7-10.
