Boasts about that he understands and knows God almighty

Jeremiah 9:1-26
Beware of your friends; do not trust your friends. For every brother is a deceiver, and every friend a slanderer. You (Jeremiah) live in the midst of deception; in their deceit they refuse to acknowledge me.
What man is wise enough to understand this? Who has been instructed by the Lord and can explain it? Why has the land been ruined and laid waste like a desert that no one can cross?
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, justices and righteousness on earth for in these I delight," declares the Lord.
The whole house of Israel is uncircumcised in heart, they has same punishment as other uncircumcised nations.
Why?
Jeremiah shares God's own deep grief at his people's sin and its tragic consequences.
Society is sick: sick s a direct result of the nation abandoning God an his laws and going their own way. So inevitable has judgment become that the professional mourners can already be called in.
All Judah and Israel are full of deceit and lie.
Despite the outward mark of his covenant, God's people have made themselves like the pagan nations around. And like them will be punished.
People pursues the wisdom, strength and rich, all of these are shame when they do not know the Lord.
How?
Real wisdom is acknowledge the Lord, it is not the wisdom on the world. What I am pursuing for? let pursuing to acknowledge the God almighty.
