Jeremiah 4:22

Only by the precious blood of the Lamb do we live. In His mercy we abide. 

Believers are justified by faith to be doers of good, not evil, in a world gone mad.

The terms foolish and silly are contrary to the terms knowledge and understanding. God described His people as impudent children. They were wise in the ways of evil, but totally deficient in knowing how to do good. NKJ Bible.

Jeremiah 4:22 (NKJV)

²² “For My people are foolish,

They have not known Me.

They are silly children,

And they have no understanding.

They are wise to do evil,

But to do good they have no knowledge.”

Romans 16:19 (NKJV)

¹⁹ For your obedience has become known to all. Therefore I am glad on your behalf; but I want you to be wise in what is good, and simple concerning evil.

1 Corinthians 14:20 (NKJV)

²⁰ Brethren, do not be children in understanding; however, in malice be babes, but in understanding be mature.
