"... the more we become like Christ, the more sensitive we are to the remaining corruptions of the flesh. As we mature in godliness our sins become more painful and more obvious to ourselves. The more we put away sin, the more we notice sinful tendencies that still need to be put away. This is the paradox of sanctification: the holier we become, the more frustrated we are by the stubborn remnants of our sin."
