Calvin on Ps 19.7-14 Even without the explicit gospel, everyone is without excuse

John Calvin’s commentary on Ps 19.7-14, “The law of the Lord. Here the second part of the psalm commences. After having shown that the creatures, although they do not speak, nevertheless serve as instructors to all mankind, and teach all men so clearly that there is a God, as to render them inexcusable, the Psalmist now turns towards the Jews, to whom God had communicated a fuller knowledge of himself by means of his word. While the heavens bear witness concerning God, their testimony does not lead men so far as that thereby they learn truly to fear him, and acquire a well-grounded knowledge of him; it serves only to render them inexcusable.”
