Nope.
Gen 22:11
And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here
am I.
Gen 22:12
And he said, Lay not thine hand upon the lad, neither do thou any thing unto him:
for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only
son from me.
Gen 22:13
And Abraham lifted up his eyes, and looked, and behold behind
him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son.
Gen 22:14
And Abraham called the name of that place Jehovahjireh: as it is said
to this day, In the mount of the LORD it shall be seen.
Gen 22:15
And the angel of the LORD called unto Abraham out of heaven the second time,
Gen 22:16
And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only
son:
Gen 22:17
That in blessing I will bless thee, and in multiplying
I will multiply thy seed as the stars of the heaven, and as the sand which
is upon the sea shore; and thy seed shall possess the gate of his enemies;
Gen 22:18
And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
God not only foreknew that Abraham would obey him, but he also foreknew that his seed would be as the stars of heaven, and that all the nations of the earth would be blessed though this act of Abraham's obedience.
For example:
Gen 18:17
And the LORD said, Shall I hide from Abraham that thing which I do;
Gen 18:18
Seeing that Abraham shall surely become a great and mighty nation, and
all the nations of the earth shall be blessed in him?
Gen 18:19
For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment;
that the LORD may bring upon Abraham that which he hath spoken of him.
Prior to the incident regarding Abraham's attempted sacrifice of Isaac, God had not only plainly declared that he knew Abraham, but he also said that he would bring upon Abraham that which he had spoken of him, and that included all the nations of the earth being blessed in him through his seed, which is Christ (Gal. 3:16).
Here is an earlier promise that God had made.
Gen 15:4
And, behold, the word of the LORD
came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.
Gen 15:5
And he brought him forth abroad, and said,
Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.
Gen 15:6
And he believed in the LORD; and he counted it to him for righteousness.
Here, God plainly foretold that Abraham's seed would be as the stars of heaven in number. Also, prior to Abraham's attempted sacrifice of Isaac, God made it clear to Abraham that in Isaac would his seed be called.
Gen 21:12
And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for
in Isaac shall thy seed be called.
Abraham had such faith in God that he was willing to sacrifice Isaac upon the altar while fully believing that God would have to raise him from the dead in order to fulfill his promise of his seed coming through Isaac's lineage.
Heb 11:17
By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten
son,
Heb 11:18
Of whom it was said, That in Isaac shall thy seed be called:
Heb 11:19
Accounting that God
was able to raise
him up, even from the dead; from whence also he received him in a figure.
When God instructed Abraham to sacrifice Isaac, he was merely trying or testing Abraham's faith, but he foreknew what Abraham would ultimately do. When he told Abraham "now I know," he was merely telling Abraham that he had passed the test. He then reiterated the same promises which he had made before Abraham's attempted sacrifice of Isaac after Abraham's attempted sacrifice of Isaac, but he obviously foreknew what Abraham would do in order to bring those promises to pass.
