“Bitterness differs from unbelief merely in the intensity and depth – in the degree – of its rebellion. As my friend Andy Farmer has pointed out, the two are distinguished simply by the difference between can’t and won’t. Unbelief says, “I can’t do this,” while bitterness says, “I won’t do this.” Unbelief tells a spouse, “You can’t change,” and bitterness declares, “You won’t change.” Unbelief claims, “God can’t affect what I like and dislike”; while bitterness says, “God won’t affect them.”
