The fact that our traditional method of extracting doctrine from Scripture does not work well on narrative does not mean that Bible stories do not send clear messages. Instead, it suggests that the way we apply our traditional method of interpretation is inadequate because we are ignoring too much of God’s Word.
The fact that God is sovereign over the distribution of gifts (1 Cor. 12:7) is no reason not to seek the gifts. God is sovereign over our food too, but though he desires to provide it for his children (see Matt. 6:25–34) and wants us to seek his kingdom first (Matt. 6:9–10, 33), he expects us to pray for him to provide our food (Matt. 6:11; 7:7–11).
