This morning we continue our series on Abraham. The story of Genesis is about God choosing a family through which God will bless all the peoples of the world. The first in that family line is Abraham. As we’ve discovered in the series so far, Abraham’s story is one of faith and failure but God accepts Abraham as he is and continues to faithfully promise that Abraham’s family will be numerous. In our reading today, God makes the same promise to Sarah – problem is they’re very old, like pushing 100, and still they don’t have a child together – surely God’s not serious, just having a laugh, it’s just not possible… is it?
