These verses are a continuation of the declaration that Jesus makes when he tells us to seek God’s kingdom above all things. For if we sincerely seek after God’s kingdom as our first priority, we will find it.  And if we knock, he will answer.  Knocking is a way of letting someone know that we are waiting outside for them to give us entry.  So, we need to let God know that we want to enter into his kingdom and he will answer us by making entry possible. Each of us may knock or ask in a different way, but we must all come to that point in our lives that we know that we want to enter his kingdom and acknowledge that he is the one who must open the door. 

But exactly what is God’s kingdom? It is everything that Jesus taught in this sermon.  If this doesn’t appeal to you, than there is little point in asking to enter, but if you are moved by what you hear, than there is no other place you will find such peace except in his kingdom.

For those in Jesus’ audience who might doubt that God would really listen to their needs he compared God to a human father.  He asked what kind of a father would give his son a stone when he asked for bread or a serpent if he asked for a fish?  Of course Jesus knew that there were fathers who did not take care of their children, but notice that he personalizes the question by specifically using them as an example?  He asks, “Is there anyone among you would not help his child?”  Obviously, only a cruel and hateful man would do such a thing, and none of them would admit to such a thing.  So his challenge becomes rhetorical.  

Jesus acknowledges that men, even though they are evil, would still take care of their families.  Then it makes perfect logic that God would be even more likely to take care of us, his own children.  Jesus’ argument is that if evil people take care of their children, how much more would a holy God  take care of his children?
