Luke 11:11-12

These two examples further enforce the point that God will respond to our prayers, and they stress that He will do so kindly (cf. Matthew 7:9-10). Since God is our heavenly Father, He will do no less than a normal earthly father would do. Even a good earthly father would not give his son who asked for a fish or an egg a snake or a scorpion. A snake can look like a fish, and scorpions sometimes bred in eggs. [Note: Edersheim, 2:242.] Such a response would be cruel rather than loving since the substitution would involve no real giving but deception and even danger.
