Matthew 7:9-11

Or what man is there among you who, if his son asks for bread, will [instead]give him a stone? Or if he asks for a fish, will [instead] give him a snake? If you then, evil (sinful by nature) as you are, know how to give good and advantageous gifts to your children, how much more will your Father who is in heaven [perfect as He is] give what is good and advantageous to those who keep on asking Him.
