Key Discussion Points & Insights

1. The Fifth Commandment's Promise

• Question 66 focuses on the "reason annexed" (the promise attached) to the fifth commandment—honoring father and mother.
• The answer explained:
  "The reason annexed to the fifth commandment is a promise of long life and prosperity as far as it shall serve for God's glory and their own good, to all such as keep this commandment." (00:03)
• Ferguson underscores: God’s promise is not just arbitrary reward, but is always conditioned by His glory and the true good of His people.

2. The Nature of God’s Promises

• The promise of “long life and prosperity” found in the commandment is not a simple guarantee but is subject to God’s wisdom and purposes.
• Key insight:
  "As far as it shall serve for God's glory and their own good"—these blessings are always in harmony with God’s plan and what He determines is truly beneficial for the believer.

3. Application for Discipleship

• Ferguson reminds listeners that understanding the promises attached to obedience is foundational for Christian growth.
• Teaching the basics—like the promise attached to the fifth commandment—is essential for nurturing both new and mature believers in the faith.
