When we yield to sin we despise the blood of Jesus Christ, and render his cross of no effect. Mortification would make us look like Christians, alas, we spare ourselves, and cry out our impotency and the power of sin; we spend our time more in fruitless complaints than in endeavours to overcome sin. Though Christ, as King, as Priest, and Prophet, takes away and destroys sin, yet do not be thinking that he will cure you as a by a charm. Must he condemn it, and you absolve it? Must he kill it, while you cherish it? Must his Spirit assist you against it, while you betray yourself into its hands? When under a temptation, and his Spirit stirs in you, he puts it to your choice, whether Christ or sin shall reign over you, and indeed this is what it comes down to, whether you will be Christians or not.
