Thematic Bible: Who became vain

So what I mean and insist upon in the Lord's name is this: You must no longer live like the heathen, with their frivolity of mind and darkened understanding. They are estranged from the life of God because of the ignorance that exists among them and their obstinacy of heart, for they have become callous, and abandoned themselves to sensuality, greedily practicing every kind of vice.

For God's anger is breaking forth from heaven against all the impiety and wickedness of the men who in their wickedness are suppressing the truth. For all that can be known of God is clearly before them; God has shown it to them. Ever since the creation of the world, his invisible nature??is eternal power and divine character??ave been clearly perceptible through what he has made. So they have no excuse, read more.
for, though they knew God, they have not honored him as God or given thanks to him, but they have indulged in futile speculations, until their stupid minds have become dark. They called themselves wise, but they have turned into fools, and for the splendor of the immortal God they have substituted images in the form of mortal man, birds, animals, and reptiles.
