Every [theological] error results from, or upon deeper reflection is traceable to, a departure in the doctrine of the Trinity.
Reformed Dogmatics, 2:288.
Ascribed to God, grace is His voluntary, unrestrained, unmerited favor toward guilty sinners, granting them justification and life instead of the penalty of death, which they deserved.
Heaven and earth and all creatures, herbs and grass, rain and drought, fruitful and barren years, meat and drink, health and sickness, riches and poverty, yea and all things declare God. There is not an atom of the universe in which God’s power and divinity are not revealed.
When you wish to do something evil, you retire from the public into your house where no enemy may see you; from those places of your house which are open and visible to the eyes of men you remove yourself into your room; even in your room you fear some witness from another quarter; you retire into your heart, there you mediate: He is more inward than your heart. Wherever, therefore, you shall have fled, there He is. From yourself, whither will you flee? Will you not follow yourself wherever you shall flee? But since there is One more inward even than yourself, there is no place where you may flee from God angry but to God reconciled. There is no place at all whither you may flee. Will you flee from Him? Flee unto Him.
The Doctrines of God.
The doctrine of God’s immutability is of the highest significance for religion. The contrast between being and becoming marks the difference between the Creator and the creature. Every creature is continually becoming. It is changeable, constantly striving, seeks rest and satisfaction, and finds this rest in God, in Him alone, for only He is pure being and not becoming. Hence, in Scripture God is often called the Rock.
