God is upright, faithful, and true, as he has shown, not only in his promises, through Christ, of
forgiveness of sins, and deliverance from everlasting death, but also, in that he has laid before us, in the Scriptures, many gracious and comforting examples of great and holy saints who of God were highly enlightened and favored, and who, notwithstanding, fell into great and heavy sins.
Adam, by his disobedience, hereditarily conveyed sin and death upon all his posterity. Aaron brought a great sin upon Israel, insomuch that God would have destroyed her. David also fell very heavily. Job and Jeremiah cursed the day in which they were born. Jonas was sorely vexed because Nineveh was not destroyed. Peter denied, Paul persecuted Christ.
These, and such like innumerable examples, does Holy Writ relate to us; not that we should live securely, and sin, relying upon the mercy of God, but that, when we feel his anger, “which will surely follow upon the sins,” we should not despair, but remember these comfortable examples, and thence conclude, that, as God was merciful unto them, so likewise he will be gracious unto us, out of his mere goodness and mercy shown in Christ, and will not impute our sins unto us.
We may also see by such examples of great holy men falling so grievously, what a wicked, crafty, and envious spirit the devil is, a very prince and good of the world.
These high, divine people, who committed such heavy sins, fell, through God’s counsel and permission, to the end they should not be proud or boast themselves of their gifts and qualities, but should rather fear. For, when David had slain Uriah, had taken from him his wife, and thereby given cause to God’s enemies to blaspheme, he could not boast he had governed well, or shown goodness; but he said: “I have sinned against the Lord,” and with tears prayed for mercy. Job also acknowledgingly says: “I have spoken foolishly, and therefore do I accuse myself, and repent.”
