It was faith that made him go to live as an emigrant in the Promised Land--as in a strange country--living there in tents with Isaac and Jacob, who shared the promise with him.

It was faith that enabled Abraham, when put to the test, to offer Isaac as a sacrifice--he who had received the promises offering up his only son,

of whom it had been said-- 'It is through Isaac that there shall be descendants to bear thy name.'

It was faith that enabled Isaac to bless Jacob and Esau, even with regard to the future.
