The Dogmatician: The Argument for God is Everywhere

[T]o the believer all things speak of God; the whole universe is the mirror of his perfections. There is not an atom of the universe in which his everlasting power and deity are not clearly seen. Both from within and from without, God’s witness speaks to us. God does not leave himself without a witness, either in nature or history, in heart or conscience, in life or lot. This witness of God is so powerful, accordingly, that almost no one denies its reality. All humans and peoples have heard something of the voice of the Lord. The consent of all peoples is confirmation of the fact that God does not leave himself without a witness; it is humanity’s response to the voice of God. —Herman Bavinck, Reformed Dogmatics

The Dogmatician: God’s Book that Cannot but Be Read

No one escapes the power of general revelation. Religion belongs to the essence of a human. The idea and existence of God, the spiritual independence and eternal destiny of the world, the moral world order and its ultimate triumph—all these are problems that never cease to engage the human mind. Metaphysical need cannot be suppressed. Philosophy perennially seeks to satisfy that need. It is general revelation that keeps that need alive. It keeps human beings from degrading themselves into animals. It binds them to a supersensible world. It maintains in them the awareness that they have been created in God’s image and can only find rest in God. General revelation preserves humankind in order that it can be found and healed by Christ and until it is. To that extent natural theology used to be correctly denominated a “preamble of faith,” a divine preparation and education for Christianity. General revelation is the foundation on which special revelation builds itself up.  —Herman Bavinck, Reformed Dogmatics
