James

“As God delights in his own beauty, he must necessarily delight in the creature's holiness which is a conformity to and participation of it, as truly as [the] brightness of a jewel, held in the sun's beams, is a participation or derivation of the sun's brightness, though immensely less in degree.”
― Jonathan Edwards

“Knowledge about Him will not do. Work for Him will not do. We must have personal, vital fellowship with Him; otherwise, Christianity becomes a joyless burden.”
― John Piper, Desiring God: Meditations of a Christian Hedonist

“God is the highest good of the reasonable creature. The enjoyment of him is our proper; and is the only happiness with which our souls can be satisfied. To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodations here. Better than fathers and mothers, husbands, wives, or children, or the company of any, or all earthly friends. These are but shadows; but the enjoyment of God is the substance. These are but scattered beams; but God is the sun. These are but streams; but God is the fountain. These are but drops, but God is the ocean.”
― Jonathan Edwards, The Works of Jonathan Edwards, Vol. 17: Sermons and Discourses, 1730-1733

“It is said that in some countries trees will grow, but will bear no fruit because there is no winter there.”
― John Bunyan
