In April 2017, Randy Alcorn taught a course at Veritas Evangelical Seminary on the subject of sexual purity. In this clip, he answers the question, "Who does the work of sanctification in our lives?"

We all know that sometimes things can be difficult in churches. I’ve gone through it, and so have most of you. I experienced it when I was a pastor for fourteen years, and I’ve experienced it in the twenty-two years since.

I always enjoy J.I. Packer. I read this in his book Great Joy, and as I meditated on it, I thought of Colossians 1:29: "For this I toil, struggling with all his energy that he powerfully works within me."

It has been my experience that most people holding this position, or at least those who actively teach it, are not open to what I believe is the clear teaching of Scripture from many passages.

In your questions you are actually asking about issues related to sanctification, therefore I would like to discuss the issue of sanctification in general, and hope to answer you along the way.
