find it in one’s heart, (not) to

To be inclined to do something; or to be unwilling to do something. This expression implies that a person is doing considerable soul-searching concerning an action, and as a cliché it may be obsolescent. It first appeared in the sixteenth century, in Sir Thomas More’s Utopia: “They cannot find in their hearts to love the author thereof.” It also appears in the King James Bible (1611) in the second Book of Samuel (7:27): “Therefore hath thy servant found in his heart to pray this prayer unto thee.”
