Whatever Paul believed would not avail the working of the tempter "within" anything.
This is "why" justification is not and can not be "of works" because "all" of our "works" are in fact tainted by the presence of indwelling sin and the internal temptations of the tempter, which place both that working and that worker "in the flesh."
2 Corinthians 1:9
But we had the sentence of death in ourselves, that
we should not trust in ourselves, but in God which raiseth the dead:
Philippians 3:3
For
we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and
have no confidence in the flesh.
James 4:
1
From whence come wars and fightings among you? come they not hence, even of your lusts that war in your members?
15 For that ye ought to say, If the Lord will, we shall live, and do this, or that.
16 But
now ye rejoice in your boastings: all such rejoicing is evil.
17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
The "foundation" of unmerited Grace and Divine Mercy is based on our 'factual needs' of same, because of our present conditions, indwelling sin, which is in fact DEMONIC. 1 John 3:8.
The same Grace that lifts us and places us into FAITH,
arouses the DEVILs to anger, and to fight because the intentions of Grace is to REVEAL and to DESTROY them. (Mark 4:15, Romans 7:7-13, Matt. 10:26, Isaiah 27:1) "For this purpose the Son of God was manifested,
that he might destroy the works of the devil." 1 John 3:8
The Divine Mercy that "allows" us to STAND IN FAITH avails DEVILs exactly nothing. They will not be recipients of Divine Mercy, but Divine Wrath and Divine Destruction.
I have every faith that the full intentions of God in Christ is to DESTROY the devil and "his works",
and this destruction will transpire IN people of faith in Jesus Christ, first.
1 Peter 4:17
For the time is come that
judgment must begin at the house of God: and if
it first begin at us, what shall the end be of them that obey not the gospel of God?
We stand under TWO JUDGMENTS.
One,
the JUDGMENT OF HIS ETERNAL LIFE, which can NOT be taken from us.
The other,
the JUDGMENT of DESTRUCTION, of all the ways and works of our adversary, and eventually, when it is TIME, the Adversary himself.
2 Thessalonians 2:8
And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
