Theologian Stephen Charnock Explains the Unchangeableness of God's Essence, Nature, and Perfections Does God's purpose change when he answers a prayer? Does his will shift when he grants repentance to sinners? Was the essence of God's son altered when he came to earth as a man? The unchangeability of God is central to the gospel, but this doctrine is frequently misunderstood by believers and debated by atheists.   In this classic essay, which has been edited and updated for a modern audience, theologian Stephen Charnock explains the doctrine of immutability. Comparing God's unchangeability to the inconstancy of all creatures, Charnock helps listeners see the foolishness of relying on a perishing world rather than an eternal and perfect God. This concise, Scripture-based essay is essential for students, pastors, and laypeople. - Written by Theologian Stephen Charnock: Abridged and lightly edited, this essay focuses on biblical and theological evidence that God is eternally unchangeable - Part of the Crossway Short Classics Series: Other titles include What Did the Cross Achieve?; The Life of God in the Soul of Man; and Fighting for Holiness  - Includes a Foreword by Mark Jones
