Bragging on God

This is what the Lord says:
"Let not the wise man boast of his wisdom
or the strong man boast of his strength
or the rich man boast of his riches,
but let him who boasts boast about this:
that he understands and knows me,
that I am the LORD, who exercises kindness,
justice and righteousness on earth,
for in these I delight,"
declares the LORD.
Jeremiah 9:23,24

Paul found this important enough to say to the Corinthian church twice.
(1 Cor. 1:31, 2 Cor. 10:17)
