God is always serious and every word He speaks is true.
Read: Jeremiah 10:10-12
But the Lord is the only true God.
He is the living God and the everlasting King!
The whole earth trembles at his anger.
The nations cannot stand up to his wrath.
11 Say this to those who worship other gods: “Your so-called gods, who did not make the heavens and earth, will vanish from the earth and from under the heavens.”
12 But the Lord made the earth by his power,
and he preserves it by his wisdom.
With his own understanding
he stretched out the heavens.
