“We are born again, we are Christians and yet sin rages within us. Our lives fall short of their potential. Our lives are not straight. They are transgressive and anomalous. There can be no bigger mistake than to forget this power and force and prevalence of sin in our lives. Indeed, we must build our whole spiritual strategy on this fact. We must remember that because there is sin in us we are spiritually inflammable. One thought from Hell, one suggestion, one opportunity to sin, can set our whole lives ablaze. That means that, as Christians, we have to live far from the boundary. We cannot live at the outer limits of the permitted.”
