God is not an employer looking for employees. He is an Eagle looking for people who will take refuge under his wings.
John PiperBe glad in the Lord and receive willingly from His Hand all that he designs for my holiness - both painful and pleasant.
John PiperPastors and missionaries (need) to know God and to find in him a Treasure more satisfying than any other person or thing or relationship or experience or accomplishment in the world.
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.
