I see. It's the spiritual equivalent to "playing the race card". Got it.
To be in/of the flesh or carnal is to be opposed to God.
Rom 8:7 Because the carnal mind is enmity against God
: for it is not subject to the law of God, neither indeed can be.
16This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other
: so that ye cannot do the things that ye would.
The minstrel boy to the war is gone,
In the ranks of death ye will find him;
His father's sword he hath girded on,
And his wild harp slung behind him;
"Land of Song!" said the warrior bard,
"Tho' all the world betray thee,
One sword, at least, thy rights shall guard,
One faithful harp shall praise thee!
