But God said to Abraham, “Do not be distressed because of the boy and because of your slave woman; whatever Sarah says to you, do as she tells you, for it is through Isaac that offspring shall be named for you.
and do not presume to say to yourselves, ‘We have Abraham as our ancestor,’ for I tell you, God is able from these stones to raise up children to Abraham.
Therefore, bear fruits worthy of repentance, and do not begin to say to yourselves, ‘We have Abraham as our ancestor,’ for I tell you, God is able from these stones to raise up children to Abraham.
