If the pursuit of God's glory is not ordered above the pursuit of man's good in the affections of the heart and the priorities of the Church, man will not be well served, and God will not be duly honored. I am not pleading for a diminishing of missions but for a magnifying of God. When the flame of worship burns with the heat of God's true worth, the light of missions will shine to the darkest peoples on earth. And I long for that day to come!
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.
John PiperWaiting for the Lord in a season of darkness should not be a time of inactivity. We should do what we can do. And doing is often God's appointed remedy for despair.
