This exhortation is also very necessary for us in the present day. We see how inclined we are by nature to indifference; and when God brings before us our sins, and then sets before us his wrath, we are not moved; and when we entertain any fear, it soon vanishes. Let us, then, know that no rest can be to us in the day of distress, except we tremble within ourselves, except dread lays hold on all our faculties, and except all our soul becomes almost rotten. And hence it is said in Psalm 4:4, “Tremble, and ye shall not sin.” And Paul also shows that the true and profitable way of being angry is, when one is angry with his sins (Ephesians 4:26,) and when we tremble within ourselves. In the same manner does the Prophet describe the beginnings of repentance, when he says, that the faithful trembled in their bowels, and were so shaken within, that even their lips quivered, and, in short, (and this is the sum of the whole,) that all their senses felt consternation and fear.
