Charles Spurgeon made this comment about the grace of God that pursued Hagar through the angel of the Lord:
I think I see her there, her eyes red with weeping, her spirit broken down with the hunger of her journey, sitting a while and refreshed a moment, and resolved not to stoop and never to go back—and then, again, shuddering at the darkness that lay before her and afraid to go on. It was in such a state as that that God met with her! To all intents and purposes she was a friendless, outcast woman. She had left the only tents where she could claim a shelter. She had gone into the wilderness—no father, no mother, no brother, no sister to care for her. She turned her back upon those who had any interest in her and now she was left alone—alone, alone in a desert land without an eye to pity or a hand to help! It was then, under those peculiar circumstances of trial and of sin commingled, that God met with her.
When you least expect it, when you least deserve it, the God of keen senses will find you and give you strength.
