The apostle gloried and rejoiced in the cross of Christ. His heart was set on it. It crucified the world to him, making it a dead and undesirable thing (Gal 6:14). The baits and pleasures of sin are all things in the world, “the lust of the flesh, the lust of the eyes, and the pride of life.” By these sin entices and entangles our souls. If the heart is filled with the cross of Christ, it casts death and undesirability on them all, leaving no seeming beauty, pleasure, or comeliness in them. Again, Paul says, “It crucifies me to the world and makes my heart, my affections, and my desires dead to all these things. It roots up corrupt lusts and affections, and leaves no desire to go and make provision for the flesh to fulfill its lusts.”
