Nothing is more vital than prayer in Christian existence, and few things are more vulnerable to neglect.
John PiperDo we eagerly long for the coming of Christ? Or do we want him to wait while our love affair with the world runs its course? That is the question that tests the authenticity of faith.
John PiperWithout extended, concentrated prayer, the ministry of the Word withers. And when the ministry of the Word declines, faith (Rom. 10:17; Gal. 3:2, 5) and holiness (John 17:17) decline. Activity may continue, but life and power and fruitfulness fade away. Therefore, whatever opposes prayer opposes the whole work of ministry.
