Introduction
Many of us talk easily about God’s love, yet say little about His holiness. R.C. Sproul begins his classic series The Holiness of God by insisting that holiness is at the core of who God is. Drawing on Isaiah’s vision in Isaiah 6:1–4, he shows that when we truly encounter the Holy One we cannot remain indifferent—and the Christian life itself flows from that vision. About 32 minutes; freely available on Ligonier’s official YouTube channel.
Preacher: R.C. Sproul (1939–2017), founder of Ligonier Ministries. Presbyterian Reformed teacher—we differ with him on baptism and church government, while gladly learning from his God-centred teaching.

Key Lessons
- Holiness is not a side attribute of God; it is at the very core of His being.
- We only see ourselves clearly when we see God as holy.
- Isaiah 6:1–4 leaves no room for casual religion: the vision of the Lord high and exalted produces awe at His majesty.
- A Christian confronted by God’s holiness cannot stay indifferent; practical Christian living flows from that vision.
Learn · Grow · Do
- Learn: God’s holiness is central, and Isaiah’s vision shows His majesty in a way that exposes us as we really are.
- Grow: Ask whether your view of God is too small—comfortable, manageable and easy to ignore.
- Do: Read Isaiah 6 aloud slowly, then note one place this week where a bigger view of God’s holiness should change how you speak or decide.
