"...Sanctification involves hard work and dependence on Christ; what I call dependent effort. And it will always mean we are dissatisfied with our performance. For a growing Christian, desire will always outstrip performance or, at least, perceived performance. What is it then that will keep us going in the face of this tension between desire and performance? The answer is the gospel. It is the assurance in the gospel that we have indeed died to the guilt of sin and that there is no condemnation for us in Christ Jesus that will motivate us and keep us going even in the face of this tension. We must always keep focused on the gospel because it is in the nature of sanctification that as we grow, we see more and more of our sinfulness. Instead of driving us to discouragement, though, this should drive us to the gospel. It is the gospel believed every day that is the only enduring motivation to pursue progressive sanctification even in those times when we don't seem to see progress. That is why I use the expression "gospel- driven sanctification" and that is why we need to "preach the gospel to ourselves every day."
