Thus the apostle Paul describes his manner of labor. He did not approach the Jews in a way to stir up their prejudice. He did not run the risk of making them his enemies by telling them in his first effort that they must believe on Jesus of Nazareth; but he dwelt on the promises of the Old Testament Scriptures, which testified of Christ, of his mission, and of his work. Thus he led them along step by step, showing them the importance of honoring the law of God. He also gave due honor to the ceremonial law, showing that Christ was the one who instituted the whole system of sacrificial service. After dwelling upon these things, making it manifest that he had a clear understanding of them himself, he brought them down to the first advent of Christ, and proved that in the crucified Jesus every specification of the prophecies had been fulfilled. This was the wisdom that Paul exercised.

Sådan skriver Paulus i sin arbejdsmetode. Han nærmede sig ikke jøderne på en måde der oprørte deres fordomme. Han løb ikke risikoen at gøre dem til sine fjender ved at fortælle dem om sin første anstrengelse for at de må tro på Jesus af Nazaret; men han dvælede ved løfterne i det gamle testamentet, som vidnede om Kristus, om hans mission og om hans arbejde. Derved ledte ham den skridt for skridt, viste dem vigtigheden af at ære Guds lov. Han gav også selv ceremoniloven den passende ære over for dem, viste at Kristus var den Ham som indledte hele offersystemet. Efter at have dvælet ved disse ting, gjorde han det klart at han selv havde en klar forståelse om dem, han bragte dem ned til Kristi første komme, og beviste at det var i den korsfæstede Jesus, at alle profetiernes enkeltheder blev opfyldt. Det var den klogskab som Paulus udøvede.
