Matthew 7:9-11
New King James Version (NKJV)
9 Or what man is there among you who, if his son asks for bread, will give him a stone? 10 Or if he asks for a fish, will he give him a serpent? 11 If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask Him!
