the prisoner, and then, comparing one with the other, gives the sentence
exactly in accordance with the guilt. If he inflicts more or less
punishment than the prisoner deserves, or for money or anything else
gives an unfair sentence, then he is an unjust judge. The judge might be
merciful in this way. The laws say that for the crime of which this
prisoner is proved guilty he can be sent to prison for a term not longer
than ten years and not shorter than five: that is, for anything between
ten and five years. The judge could give him the full ten years that the
law allows and be just. But suppose he believed that the prisoner did
not know the law and did not intend to be as wicked as he was proved; or
that it was his first offense, or that he heard the prisoner's mother,
who was old and infirm, pleading for him and saying he was her only
support; or other extenuating circumstances that could awaken sympathy:
the judge might be merciful and sentence him for the shortest term the
law allows. But if the judge dismissed every prisoner, no matter how
guilty, without punishment, he would not be a merciful but an unjust
judge, who would soon be forced to leave the court. In the same way, God
is often merciful to sinners and punishes them less than He could in
strict justice. But if He were to allow every sinner to go without any
punishment whatsoever--as unbelievers say He should do, by having no
Hell for the wicked--then He would not be just. For as God is an
Infinite Being, all His perfections must be infinite; that is, He must
be as infinitely just as He is infinitely merciful, true, wise, or
powerful.

Now He has promised to punish sin; and since He is infinitely true, He
must keep His promise.
