Key Discussion Points & Insights
1. Definition and Core Elements of Sanctification
- [00:01] Dr. Ferguson opens the episode by reciting the Catechism's answer:
- Quote: “Sanctification is the work of God's free grace, whereby we are renewed in the whole man after the image of God, and are enabled more and more to die unto sin, and live unto righteousness.”
- He highlights three main components:
- It is a work (not an act) of God’s ongoing grace.
- It affects the whole person—mind, will, and emotions.
- It involves both putting to death sin (“mortification”) and living for righteousness (“vivification”).
2. Justification vs. Sanctification
- Dr. Ferguson distinguishes between justification and sanctification:
- Justification is God’s legal declaration that a person is righteous through faith in Christ.
- Sanctification is the lifelong process of becoming more like Christ in character.
- Quote: “Justification changes our status before God; sanctification changes our hearts and lives in the here and now.” [02:40]
3. The Role of the Image of God
