Calvin says (Inst. I.2.3) that “if religion is absent from the life of men, they are then in no wise superior to brute beasts, but are in many respects far more miserable. Subject, then, to so many forms of wickedness, they drag out their lives in ceaseless tumult and disquiet. Therefore, it is worship of God alone that renders men higher than the brutes, and through it alone they aspire to immortality.”
Ought we not to pity the unbeliever then all the more and beg God to save sinners (such as we once were)?
