Now we know that everything said in the Law is addressed to those who are under its authority, in order that every mouth may be closed, and the whole world become liable to the judgment of God.
What, then, you ask, was the use of the Law? It was a later addition, to make men conscious of their wrong-doings, and intended to last only till the coming of that 'offspring' to whom the promise had been made; and it was delivered through angels by a mediator.
All these died sustained by faith. They did not obtain the promised blessings, but they saw them from a distance and welcomed the sight, and they acknowledged themselves to be only aliens and strangers on the earth.
our eyes fixed upon Jesus, the Leader and perfect Example of our faith, who, for the joy that lay before him, endured the cross, heedless of its shame, and now 'has taken his seat at the right hand' of the throne of God.
