The apostle Paul speaks of those who try to hide the truth about God. He shows why God is angry with them:
For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes [qualities], namely, His eternal power and divine nature, have been clearly perceived [seen], ever since the creation of the world, in the things that have been made. So they are without excuse (Romans 1:19-20).
Realities about God can be ”clearly perceived”! How? ”In the things that have been made.” Just looking at the wonderful creation around us helps us to know about God!
We know the wind is real by seeing how it moves dust and leaves. In a far greater way, we know things about God by the effect of His work around us. God has made it clear to those who are willing to look. That is why people have ”no excuse” when they twist the truth about God.
