Episode Overview

Main Theme:
In “Can You Keep a Secret?” Sinclair B. Ferguson reflects on the importance of faithfulness in even the smallest matters by exploring the character of Mr. Humanus from John Newton’s letters. The episode digs into why trustworthiness—especially with secrets—matters in Christian character, and connects this trait to deeper issues of the heart.

Key Discussion Points & Insights

The Characters: Mr. Austerus vs. Mr. Humanus

• Ferguson recalls how John Newton used memorable Latin names to describe various types of Christians struggling to live out the grace they sing about:
  • Mr. Austerus: The rigid, sometimes loveless Christian, discussed in previous episodes.
  • Mr. Humanus: This episode’s focus—a friendly, gregarious “people person” (00:51).

Mr. Humanus’ Struggle: Inconsistency With Secrets

• Integrity With Finances:
  • “If you trusted Mr. Humanus with your gold, there would be no risk at all. It would be perfectly safe with money. He's a model of integrity.” (01:20)
• But Not With Secrets:
  • “Entrust him with a secret, and you put your secret into the public domain. He just can't keep it to himself.” (01:29)
• Root Issue:
  • Mr. Humanus trusts himself too much and fails to control his tongue—which, spiritually, reveals a lack of control over the heart (02:43).
  • “Because spiritually, the tongue is directly connected to the heart.” (02:56)

A Personal Anecdote: Keeping a Confidence

• Ferguson recounts a moment at dinner with Christian friends where he hesitated to share a personal story without their promise to keep it confidential. To his surprise, none did—highlighting an honest self-awareness about their own ability to keep secrets (01:45).
  • “None of them promised. They were all mature Christians. Most of them were pastors... I wonder if they were thinking, you know, I don't think I can trust myself to keep Sinclair’s secret.” (01:55)

The Importance of Faithfulness in ‘Little Things’

• Loss of Trust: Once people realize you cannot keep their secrets, they will not come to you with their true struggles, and you’ll be left wondering why you’re excluded (03:15).
• Faithfulness Principle:
  • “Keeping secrets is a small thing. Failing to keep them is a big thing, because faithfulness isn't really faithfulness unless it's faithfulness in everything.” (03:33)
• Faithful in All Things:
  • “Being faithful in the big things doesn't minimize the importance of being faithful in the small things.” (03:44)

Why Some People Are Trusted

• Guarding Hearts and Lips:
  • Some members of the church become confidants because “they guard their hearts and their lips as though they were Fort Knox.” (04:07)
• Lesson for Listeners:
  • “You and I need to learn to do the same.” (04:14)

Scriptural Connection

• Ferguson ends by quoting Jesus:
  • “One who is faithful in very little is also faithful in much.” (04:19)
