(from Dr. Chris Craig, FBC Ruston, these are my notes.)
The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, 19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
1. God Never Approves of Wrong (v. 18)
Wrath = 'controlled anger' in the Bible times and a common word then; a sad, rational, proper anger
a - "against all godlessness" -- a lack of reverence toward God and the things of God
b - wickedness - toward others
2. Wrong Behavior Supresses Truth
3. We Are Without Excuse (19-20)
Nature points us to God
Ps. 19: 1-3 -- "the skies declare..."
4. What Does This Mean?
a - God judges men on the knowledge we have (Luke 12:47 -- the servant who knows vs. servant who does not)
b - John 14:6 -- "no man but thru me..."
Ps 19: 7-8 -- 'special revelation" ... we have the Bible
Col 1:15 -- "He is the image of God..."
You and I have heard clearly and are without excuse
