Elucidates the progress made toward God's plan to turn a small family into a mighty nation, in spite of Isaac and Jacob's weakness and sinfulness. 'Our God delights in writing straight with a crooked pencil,' says Iain Duguid. The lives of Isaac and Jacob are vivid examples of that principle. Time and again God displays his grace and glory by overcoming their weakness and sinfulness. In this addition to the Gospel According to the Old Testament series, we see once more how the message of Scripture converges on Jesus. Readers can take encouragement in the midst of their own shortcomings that the gospel triumphs not through human might or goodness but through God's relentless grace.
