This last great act of faith we see from Abraham is the finding of a wife for his son Isaac. The fulfillment of the promise God gave him, that through his seed he would bless the nations, depended on Isaac finding the right wife.
Likewise, one of the greatest steps of faith we will make in our lives is choosing who we will marry. The courtship of Isaac and Rebekah provides valuable wisdom of how we should go about looking for a spouse.
