Importunity

And he said unto them, Which of you shall have a friend, and shall go unto him at midnight, and say unto him, Friend, lend me three loaves; For a friend of mine in his journey is come to me, and I have nothing to set before him? And he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee. I say unto you, Though he will not rise and give him, because he is his friend, yet because of his importunity he will rise and give him as many as he needeth. And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. (Luke 11:5-10 KJV)

Importunity.
The state or quality of being importunate;
Persistence in solicitation.

Knock, knock, knock!
Father,
Father!
You who made me
Know why I approach Your Throne.

I trust You.
I know that the times that test us
Can teach us strength,
And patience,
And endurance.
Limited as I am
To my own understanding and perspective,
I pray for alleviation
For my friend.

Heal her, Lord.
Maker of bodies
That serve as Your Temples,
Please heal my friend.
Grant her fortitude and endurance,
Patience and wisdom
During the time of trial.
Grant me forethought
To anticipate needs
And cheerfulness
To lighten her heart.

Father,
I knock and knock...
I will continue to knock.
Please open the door.
