Yes indeed – only by a spiritual connection with God by grace through faith can our spirit overcome the passions of the flesh.
No argument at all that we see being ‘in-the-flesh’ or ‘of-the-flesh’ many times as being associated with sinfulness.
However, we need to be careful here though by equating all flesh as sinful.
Gen 2:24
[24] Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh.
Gen 7:15
[15] They went into the ark with Noah, two and two of all flesh in which there was the breath of life.
Gen 9:17
[17] God said to Noah, “This is the sign of the covenant which I have established between me and all flesh that is upon the earth.”
Gen 17:11,13-14
[11] You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you.
[13] both he that is born in your house and he that is bought with your money, shall be circumcised. So shall my covenant be in your flesh an everlasting covenant.
[14] Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant."
Ex 12:8
[8] They shall eat the flesh that night, roasted; with unleavened bread and bitter herbs they shall eat it.
Note that Jesus is the sacrificed lamb.
This is a Catholic’s connection to the Eucharist.
(but that is a topic for another time)
2 Kngs 5:10
[10] And Eli’sha sent a messenger to him, saying, “Go and wash in the Jordan seven times, and your flesh shall be restored, and you shall be clean.”
So flesh *can *be clean.
Ps 136:25
[25] he who gives food to all flesh,
for his steadfast love endures for ever.
He feeds our flesh out of love.
Ps 145:21
[21] My mouth will speak the praise of the LORD,
and let all flesh bless his holy name for ever and ever.
If flesh itself is evil, it cannot bless anything.
Isa 66:23
[23] From new moon to new moon,
and from sabbath to sabbath,
all flesh shall come to worship before me,
says the LORD.
Here, the ‘flesh’ worshiping God is not evil.
Jer 32:27
[27] "Behold, I am the LORD, the God of all flesh; is anything too hard for me?
Is God the god of sinfulness or righteousness?
‘flesh’ does not always equal ‘sin’ in scripture.
2 Cor 4:11
[11] For while we live we are always being given up to death for Jesus’ sake, so that the life of Jesus may be manifested in our mortal flesh.
Gal 2:20
[20] I have been crucified with Christ; it is no longer I who live, but Christ who lives in me; and the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
Eph 5:29
[29] For no man ever hates his own flesh, but nourishes and cherishes it,
as Christ does the church,
Phil 1:21-24
[21] For to me to live is Christ, and to die is gain.
[22] If it is to be life in the flesh, that means fruitful labor for me. Yet which I shall choose I cannot tell.
[23] I am hard pressed between the two. My desire is to depart and be with Christ, for that is far better.
[24] But to remain in the flesh is more necessary on your account.
Better to be in heaven, but not that the flesh is portrayed as evil here.
Col 1:24
[24] Now I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ’s afflictions for the sake of his body, that is, the church,
It looks like my flesh might actually have a fruitful purpose: to complete what is lacking in Christ’s afflictions for the sake of HIS body.
Phlm 1:16
[16] no longer as a slave but more than a slave, as a beloved brother, especially to me but how much more to you, both in the flesh and in the Lord.
Not ‘flesh’ versus ‘the Lord’.
There are more examples of where ‘flesh’ is not equated with ‘sin’ or ‘evil’, but I’ll wrap up with this…
John 1:14
[14] And the Word became **flesh **and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father.
