Lukewarmness is stated to be the object of God’s disgust and aversion; zeal and love, on the other hand, are the objects of His favor and delight. The taking away of the heart of stone, and the implanting of a warmer and more tender nature in its stead is specifically promised as the effect of His returning favor and the work of His renewing grace. – William Wiberforce
