In fine, the system He pursues to inspire fear is the source of salvation. And it is the prerogative of goodness to save: “The mercy of the Lord is on all flesh, while He reproves, corrects, and teaches as a shepherd His flock. He pities those who receive His instruction, and those who eagerly seek union with Him.” And with such guidance He guarded the six hundred thousand footmen that were brought together in the hardness of heart in which they were found; scourging, pitying, striking, healing, in compassion and discipline: “For according to the greatness of His mercy, so is His rebuke.” For it is indeed noble not to sin; but it is good also for the sinner to repent; just as it is best to be always in good health, but well to recover from disease. So He commands by Solomon: “Strike thou thy son with the rod, that thou mayest deliver his soul from death.” And again: “Abstain not from chastising thy son, but correct him with the rod; for he will not die.”
