will, and it is man's duty to accept the divine interpretation.
The more unaccountable to man the divine interpretation be,
the better calculated it is to bring to the fore in man's con-
sciousness the necessity that he think and live covenantally,
that is, in the obedience of personal devotion to his God.
As God gave a special meaning to one of the trees of the
garden, which it did not possess according to the ordinary
constitution of things, making it the tree of forbidden fruit;
as God gave a peculiar significance to certain meats in the
ceremonial of the Old Testament, making them unclean; so
now God effectively redefined the life of Isaac, making it the
life to be sacrificed.
Confronted with a test which accents the purely covenantal
nature of the obedience which must well from the hearts of
his spiritual seed, the father of believers must not apply an
abstract principle which forbids human sacrifice. For the
child of the Covenant must listen only to his Father's voice.

If Abraham does substitute that dictum of an idol ethic for
the living voice of his Father at this juncture, he will find
consistency demanding of him in the Judgment that he refuse
the Atonement which his Father has provided. For the
ethical principles operative in the Father's sacrifice of His Son
in the fulness of time are the same as those involved in the
"sacrifice" of Isaac. The latter, indeed, constitutes an intru-
sion of that ethic within the Old Testament and, as expected,
it attaches to an event which typifies the Cross. At the same
time,
the fact that what was actually sacrificed by Abraham
was the divinely provided substitute, advises us of the in-
adequacy of sinful human life to serve as an atoning sacrifice.

Since the Father speaks to His children today only in the words of
the completed Scriptures, we are never tested in the peculiar manner of
Abraham's trial of faith; that is, there are now no immediate divine
revelations whose authority we might defy by idolizing previous revelation.
It is, however, also true that the "now", the present dispensation, is not
a closed and perpetual order but an age open to imminent invasion and
termination by the coming of the day of the Lord. The child of the Cove-
nant, therefore, must live in expectant hope of "the appearing of the
glory of the great God and our Saviour Jesus Christ" and, when confronted
with that ultimate theophany, he must be ready to heed the new demands
of his God though they annul Scriptural requirements in force during the
age just a moment ago waxed old and vanished away.
