The legal demand of our sin debt is divine punishment. Sin must be paid for. But here we discover a glorious truth: even though you and I are entirely and solely responsible for our sin debt, God makes provision for the debt himself by nailing that debt to the cross of Christ and satisfying its demands. When Jesus was crucified on the cross, he paid for all of our sin. Every instance of treasuring images of sexual immorality in our hearts, every eager glance at pornography, all of our lustful gawking — everything — is paid for by Jesus in his death for sinners.
