"My friend, do you think that God is asleep?
Do you feel that He has gone to bed when you pray, and you cannot get Him up?
Do you believe that He does not want to answer your prayers?
God does want to answer your prayers and He will.
That is what this parable is saying. You do not have to storm the gates of heaven or knock down the door of heaven in order to attract God's attention.
God is not reluctant to hear and answer you.
God tells us in Isaiah 65:24, "And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear." God wants to hear and answer."
