Christian Cryder: “[O]ur hearts are sanctified (changed, perfected) only as we repeatedly embrace the gospel in faith. Luther offers an analogy from marriage: faith is the wedding ring which unites us to Christ; by it he inherits all that is ours (sin, unrighteousness), and we inherit all that is his (glory, righteousness). Our desires are transformed as we focus on Christ’s magnificent, ravishing love for us.
“Tim Keller sees in this the fundamental dynamic for Christian living: “We are saved by believing the gospel, and then we are transformed in every part of our mind, heart, and life by believing the gospel more and more deeply as our life goes on.” The reality of my union with Christ funds my spiritual change; the indicative drives the imperative. We need to constantly remind ourselves of this truth. We clean ourselves up, then, not be trying harder or by doing good works, but by believing God’s promises more and more.
“It is important to note that this concept of sanctification by faith is fundamentally biblical. As Dr. Richard Gaffin says, “What faith will always understand is that the path of sanctification has on it the same signposts as the path for justification – grace alone through faith alone in Christ alone.”
