“Doctrine is the foundation of true delight. And if we do not get our doctrine of God right, we will destroy the foundations of delight. Joy may flourish for a generation when the root is severed, but in the end, delight in God will die without true doctrine. And both means of glorifying–seeing and savoring–God will vanish.” (John Piper)
