His faith is only shown by his works. Because he believed in God he
went and did things which he would not have done if he had not
believed in God. Of him it is written, that he obeyed the voice of
the Lord, and kept his charge, his commandments, his statutes, and
his laws.

In a word, he had not merely found out that there was one God, but
that that one God was a good God, a God whom he must obey, and obey
by being a good man. Therefore his faith was counted to him for
righteousness, because it was righteousness, and made him do
righteous deeds.

He believed that God was helping him; therefore he had no need to
oppress or overreach any man. He believed that God's eye was on
him; therefore he dared not oppress or overreach any man.

His faith in God made him brave. He went forth he knew not whither;
but he had put his trust in God, and he did not fear. He and his
three hundred slaves, born in his house, were not afraid to set out
against the four Arab kings who had just conquered the five kings of
the vale of Jordan, and plundered the whole land. Abraham and his
little party of faithful slaves follow them for miles, and fall on
them and defeat them utterly, setting the captives free, and
bringing back all the plunder; and then, in return for all that he
has done, Abraham will take nothing--not even, he says, 'a thread or
a shoe-latchet--lest men should say, We have made Abraham rich.'
And why?

Because his faith in God made him high-minded, generous, and
courteous; as when he bids Lot go whither he will with his flocks
