, passage=To whom thus Michael. Doubt not but that sin
Will reign among them, as of thee begot;
And therefore was law given them, to evince
Their natural pravity , by stirring up
Sin against law to fight: that when they see
Law can discover sin, but not remove,
Save by those shadowy expiations weak,
The blood of bulls and goats, they may conclude
Some blood more precious must be paid for Man;
Just for unjust; that, in such righteousness
To them by faith imputed, they may find
Justification towards God, and peace
Of conscience; which the law by ceremonies
Cannot appease; nor Man the mortal part
Perform; and, not performing, cannot live.}}
