You still trusting in the flesh.
Yes, as much as Saul, maybe even more:
20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me:
and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. Galatians 2:20.
And what did Saul mean about living in the flesh as a Jewish Christian?
3 For
we are the circumcision,
which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
4 Though I might also have confidence in the flesh.
If any other man thinketh that he hath whereof he might trust in the flesh, I more:
5
Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee;
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
Philippians 3:3–6.
Saul trusted in his flesh as the seed of Abraham, Isaac, and Jacob/Israel. The sons of Jacob were twelve sons from four wives. Benjamin was born to Rachel, the woman Jacob worked for Laban to win her in marriage, but Laban gave him Leah instead and Jacob had to work another seven years to get Rachel as wife.
So, why was Saul especially proud of his "flesh" being a Hebrew of Hebrews is easy to explain and here are a couple of points to which Saul may have been referring:
As the family journeyed from Bethel, Rachel went into hard labor near Ephrath (Bethlehem). In her final moments, as her soul was departing, she named the child
Benoni, which means "son of my sorrow." However, Jacob, exercising his authority as the patriarch, renamed him
Benjamin (
Binyamin).
Ben-oni: This name reflected Rachel's personal physical and emotional pain.
Binyamin (Benjamin): Usually translated as
"Son of the Right Hand." In Hebrew,
Yamin (Right) often signifies strength, favor, or the south. Benjamin was the only son of Jacob born specifically
in the Land of Promise (Eretz Yisrael). Because of this, the Midrash often highlights
Benjamin’s unique purity, as he was not part of the exile in Padan-aram. It is a significant point in Scripture that the territory allotted to the tribe of Benjamin eventually included the site of the Holy Temple in Jerusalem. This is seen as a fulfillment of Moses' blessing in
Deuteronomy 33:12, where Benjamin is called the "beloved of the Lord" who dwells between God's shoulders.
What a legacy! Rachel died and was buried "in the way to Ephrath," and Jacob set a pillar upon her grave. To this day,
Kever Rachel (Rachel's Tomb) remains a site of deep significance in Jewish prayer and thought, representing
the mother who weeps for her children.
We can get more into Saul's personal history as a "Hebrew of Hebrews" circumcised the eighth day, of the stock of Israel. No other son of Jacob was given this "medal of honor" of being "beloved of the LORD" and who dwells
between God's shoulders.
"If any other man thinketh that he hath whereof he might trust in the flesh, I more."
Saul was very proud of being a son of Abraham, Isaac, and Jacob and he even says outright that "some might trust in the flesh,
more" and he proceeds to describe those things that was given to Benjamin by God.
20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. Galatians 2:20.
So, let's stop trying to accuse me of something the apostle Saul himself was guilty of.
Saul says: "and the life which I now live in the flesh I live by the faith of the Son of God."
Saul's life was lived "in the flesh" as a son of Abraham, the man in whom the covenant is named after.
Gentiles do not have this. They cannot say with Saul they are of the BIOLOGICAL SEED of Abraham. The best they can do is say they are of the seed of Japheth or Ham. Two men of Noah's loins that do not have covenant with God.
What a legacy Saul was proud of. A Hebrew of Hebrews! Wow!
