“If I must boast, I will boast of the things that show my weakness” (v30). Paul’s opponents, the “false apostles” leading the Corinthians astray, were taking advantage of the believers (v17-23). Paul was angry that the Corinthians admired these “deceitful workmen” (v13) who demanded money, boasted about their accomplishments, and put themselves on a pedestal. The Corinthians, like everyone, eagerly followed attractive, self-promoting leaders, but Paul said this was not Jesus’ way. He described a life of suffering, of pastoral concern, and of humility (v23-29).
“Are they servants of Christ?” (v23). Jesus “made himself nothing” in order to save us (Phil 2:7). Those who truly serve in His name are marked by the same love and humility.
