Matt Waymeyer has posted the following excellent outline on general revelation on his blog.
The Definition of General Revelation
General revelation is the universal self-disclosure of God by which He makes Himself known to all people everywhere (Ps 19:1-6; Rom 1:18-23; 2:14-15; Acts 14:17).
The Means of General Revelation
1. God’s Creation (Ps 19:1-6; Rom 1:19-21)
- the heavens (Ps 19:1-4a)
- the sun (Ps 19:4b-6)
- the world (Rom 1:20a)
- “what has been made” (Rom 1:20b)
2. God’s Provision (Acts 14:17)
- the provision of rain (Acts 14:17a)
- the provision of fruitful seasons (Acts 14:17b)
- the provision of food (Acts 14:17c)
3. Man’s Conscience (Rom 2:14-15)
- “the Law written in their hearts” (Rom 2:15a)
- “their conscience bearing witness” (Rom 2:15b)
The Audience of General Revelation
1. All Men without Exception
- “all the earth” (Ps 19:4a)
- “to the end of the world” (Ps 19:4b)
- “nothing is hidden from its heat” (Ps 19:6)
2. All Men without Distinction
- Jew and Gentile (Rom 2:14-15; Acts 14:17)
- Righteous and Wicked (Acts 14:17; cf. Matt 5:45)
The Content of General Revelation
1. The Existence of God (Rom 1:19-25)
- “His divine nature” (20)
- “they knew God” (21)
- “the truth of God” (25)
2. The Glory of God (Ps 19:1a; Rom 1:19-23)
- “the glory of God” (Ps 19:1a)
- “the glory of the incorruptible God” (Rom 1:23)
- “that which is known about God” (Rom 1:19)
- “His invisible attributes” (Rom 1:20)
3. The Power of God (Ps 19:1b; Rom 1:20)
- “the work of His hands” (Ps 19:1b)
- “His eternal power” (Rom 1:20)
4. The Goodness of God (Acts 14:17)
- “He did not leave Himself without witness, in that He did good”
5. The Law of God (Rom 2:14-15)
- “the things of the Law” (14)
- “the work of the Law” (15)
The Outcome of General Revelation
1. The Comprehension of Truth (Rom 1:19-21)
- what “is known about God is evident within them” (19a)
- “God made it evident to them” (19b)
- “they knew God” (21)
2. The Suppression of Truth (Rom 1:18-25)
- “men who suppress the truth in unrighteousness” (18)
- “they did not honor Him as God or give thanks” (21)
- “they became futile in their speculations” (21b)
- “their foolish heart was darkened” (21c)
- “they became fools” (22)
- “exchanged glory of incorruptible God for image” (23)
- “exchanged the truth of God for a lie” (25)
- “worshiped/served creature rather than Creator” (25)
3. The Culpability of Unbelievers (Rom 1:18-23)
- “so that they are without excuse” (20)
The Limitations of General Revelation
1. Not Detailed in its Content (Ps 19; Rom 1-2; Acts 14:17)
- the existence of God (Rom 1:19-25)
- the glory of God (Ps 19:1a; Rom 1:19-23)
- the power of God (Ps 19:1b; Rom 1:20)
- the goodness of God (Acts 14:17)
- the law of God (Rom 2:14-15)
2. Not Salvific in its Effect (Rom 1:20; cf. 10:14)
- fails to save the unbeliever (1:20; cf. 10:14)
- renders him “without excuse” before God (1:20)
