Romans 1:18-32, An Overview: The Evident Guilt of Mankind
THE EVIDENT GUILT OF MANKIND
Romans 1:18-32
In Romans 1:18–32, the Apostle Paul lays out a sobering progression of human rebellion against God. Far from being ignorant, humanity has clear evidence of God’s existence and character through creation itself. The world often argues that people cannot be held responsible for sin because God is invisible and difficult to understand. But Paul dismantles this excuse entirely.
Romans 1:18-32 Overview | Romans 1:18-21 1rst Stage | Romans 1:22-24 2nd Stage | Romans 1:25-32 3rd Stage
The world has long argued that since man has difficulty understanding truth and God, he should not be held responsible for his sin. Man claims to be “ignorant and innocent” of knowing an invisible God and His standards. Usually, they cite a remote tribe in an obscure part of the world. But more often, they are just making an excuse, saying, “What I don’t know won’t hurt me.” Man, in every case, will try to find a comfortable place to hide from guilt and impending judgment (c.f. John 3:19-20) and continues in his rebellion against God. However, God repeatedly insists that man is accountable for his sinful behavior. Let’s examine more closely the three stages outlined in these verses, which reveal both God’s great patience and His wrath.
Each stage is visible not only in segments of our society but has also become largely accepted and seen as normal. They are only considered normal because we observe them regularly, as God consistently responds to man’s rebellion in the same way. Although Calvin believes Paul introduces a new topic in verse 18, the parallel language makes it clear that Paul continues his discussion of God's revelation and mankind's accountability.
The biblical argument is this: In 1:18-19, God’s righteousness is revealed through the person and message of Jesus Christ (discussed earlier in 16-17). God’s intense anger is evident in the lives of sinful people under His judgment. God hasn’t been hiding anything from us; instead, He is openly showing His ways so that we may turn back, for repentance leads to hope in Christ. Paul, in verses 19-20, expands on this idea and depicts man’s spiritual struggle with God. This struggle provides clear evidence that man naturally knows some things about God and, as a result, is accountable to Him.
They demonstrate that society follows a clear process closely connected to man’s openness to God’s truth. The more openly truth is rejected (and the more truth is revealed through the Bible), the more immoral the conditions in a society become. Each stage begins with a certain understanding of truth, which is then abandoned or exchanged (see the three downward stages: 1:23-24; 25-26; 26-28).
God does not want humans to sin and rebel against Him, but if humans reject God’s grace, the Lord will hand them over to their true desires. Human beings, by God’s mercy, do not fall all at once like the angels, even though God could have made it so. Though we deserve swift, complete judgment, God instead provides stages or pauses in which He enables humans to recover from their fall on the slippery, immoral slope. The good news for us is that with the right response, we can, through God’s grace, return to a proper way of living. Looking more broadly, we all, in some ways, have been rescued from different points of decline seen in these stages. This is the promise in Romans 1:16, “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes.”
The three stages of man’s moral decline are carefully presented in Romans 1:18-32. At each stage, there is a departure from truth and a resulting consequence. There are two steps in the process of rejecting God: rejection and adoption. Man first rejects God’s truth and then adopts false ideas.
This process of rejecting truth speeds up as more truth is disclosed. If a child dislikes a certain vegetable in small amounts, there is no way he will be happy with a plate full of it! A common counterargument is that if tribal people knew more truth, they would respond more easily to it, but this conflicts with the natural process of rejection. Without God’s intervening grace, their tendency to resist and reject truth grows stronger.
