Genesis 15:5-6
The LORD brought him [Abraham] outside and said, "Look toward heaven and count the stars, if you are able to count them." Then he said to him, "So shall your descendants be. "And he believed the LORD; and the LORD reckoned it to him as righteousness.

Gracious God,
    keeper of all promises;
Give us the faith of Abraham
     so we may be made holy in your sight.
In the name of the one who embodied this faithfulness,
        Jesus the Christ.
                                                            Amen.
