In 2 Corinthians 5:11-15, Paul gives two motives for why he seeks to persuade men of the truth about Jesus.
First, “We know what it is to fear the Lord” (2 Cor 5:11), which is a reference to the future judgment of Christ that he previously discussed (2 Cor 5:10). Every believer must appear before the judgment seat of Christ for evaluation.
Second, “For Christ’s love compels us, because we are convinced that one died for all” (2 Cor 5:14). Paul is thinking here of the cross, on which Christ died for sinners as a substitutionary sacrifice.
Paul demonstrates great zeal in his ministry, and he mentions two motives (though perhaps there are more) that drive him: he will face the future judgment of Christ for evaluation, and he knows that Jesus died for sinners.
It would be good if Paul’s motivations were our motivations as well. So does the past death of Christ for sinners and the future evaluation of all believers motivate you?
