This excerpt from Kierkegaard's Fear and Trembling discusses the Knight of Faith. What are the differences between the knight of faith and the knight of infinite resignation?
Preparation
III
It was in the early morning. Abraham arose betimes; he kissed Sarah, the
young mother, and Sarah kissed Isaac, her joy, her delight for all
times. And Abraham rode on his way, lost in thought – he was thinking
of Hagar and her son whom he had driven out into the wilderness. He
ascended Mount Moriah and he drew the knife.
It was a calm
evening when Abraham rode out alone, and he rode to Mount Moriah. There
he cast himself down on his face and prayed to God to forgive him his
sin in that he had been about to sacrifice his son Isaac, and in that
the father had forgotten his duty toward his son. And yet oftener he
rode on his lonely way, but he found no rest. He could not grasp that it
was a sin that he had wanted to sacrifice to God his most precious
possession, him for whom he would most gladly have died many times. But,
if it was a sin, if he had not loved Isaac thus, then could he not
grasp the possibility that he could be forgiven: for what sin more
terrible?
When the child is to be weaned, the mother is not
without sorrow that she and her child are to be separated more and more,
that the child who had first lain under her heart, and afterwards at
any rate rested at her breast, is to be so near to her no more. So they
sorrow together for that brief while. Happy he who kept his child so
near to him and needed not to sorrow more!
