Merely In The Flesh

Jeremiah 9:23-26 ESV
Thus says the Lord: “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, 24 but let him who boasts boast in this, that he understands and knows me, that I am the Lord who practices steadfast love, justice, and righteousness in the earth. For in these things I delight, declares the Lord.”
25 “Behold, the days are coming, declares the Lord, when I will punish all those who are circumcised merely in the flesh— 26 Egypt, Judah, Edom, the sons of Ammon, Moab, and all who dwell in the desert who cut the corners of their hair, for all these nations are uncircumcised, and all the house of Israel are uncircumcised in heart.”

When we understand and know the Lord we then can see the foolishness of our wisdom, the weakness of our strength, and the poverty of our riches when we turn our eyes toward Him.

It is the heart of a spirit touched by and in touch with the Holy Spirit that has the life of the Lord poured out and marking that person with the seal of God.
