able to raise him up
Hebrews 11:19
11:19 able to raise him up. Abraham had assured his servants that he and Isaac would return (Genesis 22:5), even though he fully intended to slay Isaac in obedience to God, simply because he believed God. Thus, even in a time when no one had ever been raised from the dead, Abraham believed God would raise Isaac up in order to keep His promise. Such was the faith of Abraham!
