Matthew Henry on Jeremiah 9:23-26

In this world of sin and sorrow, ending soon in death and judgement, how foolish for men to glory in their knowledge, health, strength, riches, or in any thing which leaves them under the dominion of sin and the wrath of God! and of which an account must hereafter be rendered; it will but increase their misery. Those are the true Israel who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh. Let us prize the distinction which comes from God, and will last for ever. Let us seek it diligently.
