{Accounting} (logisamenos). First aorist middle
participle of logizomai. Abraham had God's clear command that
contravened God's previous promise. This was his solution of his
difficult situation. {God is able} (dunatai ho theos). God had
given him Isaac in his old age. God can raise him from the dead.
It was Abraham's duty to obey God. {In a parable} (en
parabol(8869)). See already  9:9  for parabol(885c). Because of
(hothen, whence) Abraham's superb faith Isaac was spared and so
he received him back (ekomisato) as almost from the dead. This
is the test that Abraham stood of which James speaks ( Jas
2:23 ).
