In the Bible, “father” usually evokes positive thoughts: life, care, protection, discipline and respect. Unfortunately, for many people the word “father” stirs up negative feelings: harshness, abuse, neglect and absence. Yet most of us sense what fathers ought to be. Those without fathers want to know them, they long for loving relationships. Jesus knows how much “evil” we experience, how imperfect our families are. So, when the disciple says, “Lord, teach us to pray” (Luke 11), Jesus compares our imperfect fathers with the perfect Father.
What father among you, if his son asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask Him! (Luke 11:11-13)
In Luke 11, Jesus was emphasizing again a lesson already given in Matthew 7.
Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and the one who seeks finds, and to the one who knocks it will be opened. Or which one of you, if his son asks him for bread, will give him a stone? Or if he asks for a fish, will give him a serpent? If you then, who are 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! (Matthew 7:7-11)
The phrase “how much more” makes the point. Even bad people can do good things. How much more will your good Father help His children!
