Paul could be as zealous as any of the most zealous, in his allegiance to the law of God, and show that he was perfectly familiar with the Old Testament Scriptures. He could dwell upon the types and shadows that typified Christ; he could exalt Christ, and tell all about Christ and His special work in behalf of humanity, and what a field he had to explore. He could advance most precious light upon the prophecies, that they had not seen; and yet he would not offend them. Thus the foundation was laid nicely, that when the time came that their spirits softened, he could say in the language of John, Behold in Jesus Christ, who was made flesh, and dwelt among us, the Lamb of God, who taketh away the sins of the world.{6BC 1089.1}

Paulus kunne være lige så ivrig som de mest ivrige, i sin troskab mod Guds lov, og vise at han var helt fortrolig med de gammeltestamentlige skrifter. Han kunne dvæle ved symbolerne og afskygningerne som afbillede Kristus, han kunne ophøjede Kristus, og fortælle alt omkring Kristus og Hans særlige arbejde for menneskenes skyld, og hvilken en mark han skulle ud på. Han kunne gå frem i det mest dyrebare lys i profetierne, som de ikke havde set; og alligevel ville han ikke fornærme dem. Sådan blev grundlaget lagt allerbedst, at når tidspunktet kom, blev de bløde om hjertet, og kunne tale i Johannes sprog: Se på Jesus Kristus, som blev gjort til kød, og boede iblandt os, Guds Lam, som bærer verdens synd.
