In a helpful article over at Ligonier, Sinclair Ferguson seeks to answer for us and for a particular young minister the question: How do you mortify sin? 

Ferguson points readers to a careful examination of several passages: Romans 8:13; Romans 13:8–14; 2 Corinthians 6:14–7:1; Ephesians 4:17–5:21; Colossians 3:1–17; 1 Peter 4:1–11; 1 John 2:28–3:11. Then, Ferguson gives four practical and helpful admonitions along with careful explanation of each. Here is a summary of his points:

  1. Learn to admit sin for what it really is.
  2. See sin for what your sin really is in God’s presence.
  3. Recognize the inconsistency of your sin.
  4. Put sin to death (Col. 3:5).
