As to the object of your affections, in an especial manner, let it be the
cross of Christ, which has exceeding efficacy towards the disappointment
of the whole work of indwelling sin: “God forbid that I should
glory, save in the cross of our Lord Jesus Christ, whereby the world is
crucified unto me, and I unto the world” (Gal. 6:14). The cross of
Christ he [Paul] gloried and rejoiced in; this his heart was set upon; and
these were the effects of it—it crucified the world unto him, made it a
dead and undesirable thing. The baits and pleasures of sin are taken all
of them out of the world. . . . If the heart be filled with the cross of
Christ, it casts death and undesirableness upon them all; it leaves no
seeming beauty, no appearing pleasure or comeliness, in them. Again,
says he, “It crucifies me to the world; makes my heart, my affections,
my desires, dead unto any of these things.” It roots up corrupt lusts and
affections, leaves no principle to go forth and make provision for the flesh, to fulfill the lusts thereof.
Labor, therefore, to fill your hearts with
the cross of Christ . . . that there may be no room for sin.
