Persevering in Prayer - Piper Quote

"The point is not to finally break down God's resistance but to discover, by patient prayer, God's wisdom as to the way and time the prayer should be answered. He is not disinclined to help His children and glorify His name. He simply knows better than we do when and how the answer should come. Therefore, our persistence in prayer shows both our confidence that God is our only hope and that He will act in the best way and the best time in response to our persistent pleas."
