Charles H. Spurgeon on Psalms 98:2

Made known: He says not, He shewed, but He made known. Adam knew him, and predicted concerning him, "A man shall leave father and mother, and shall cleave to his wife, and they twain shall be one flesh." Abel knew him, who offered the lamb; Seth knew him, and called upon him; Noah knew him, and saved all the race in the ark; Abraham knew him, and offered up his son to him. But because the world had forgotten him and worshipped idols, the Lord made his Jesus known, when he sent the Word in flesh to the Jews, and revealed his righteousness to the nations, when he justified them through faith. Wherefore did he reveal him to the nations? Because of his mercy. Wherefore old he make him known to the Jews? Because of his truth, that is, his promise. Honorius, the Continuator of Gerhohus.
