The second track on "Shot of Love" fits, again, somewhere between in secular and religious territory. A slight but jaunty, Tex-Mex number, "Heart of Mine" is a love song, Dylan's first in several years, but it is founded on Jeremiah 17:9, "The heart is deceitful above all things, and desperately wicked: who can know it?" Instead of singing to a person of interest, the narrator addresses his own "heart", trying to tame his own impulses and emotions in fear of getting hurt.
