Having a sinful nature means we are wrong (in comparison to how God originally created humans), it does not mean we are bent toward evil. We are genetically corrupt and spiritually dead. Being spiritually dead means we have no capacity whatsoever to know God even exists. .
you just contradicted yourself. One who is spiritually dead to Christ is the slave of sin, of sinning, a slave of the devil.
That person "does not submit to the LAW of God neither indeed CAN they" Romans 8:4-9
Romans 6
15 What then? Shall we sin because we are not under law but under grace? May it never be! 16 Do you not know that
when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness? 17 But thanks be to God that though you were slaves of sin, you became obedient from the heart to that form of teaching to which you were committed, 18 and having been freed from sin, you became slaves of righteousness.
Eph 2
And
you were dead in your trespasses and sins, 2 in which you formerly
walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the
sons of disobedience. 3 Among them we too all
formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest.
The Sinful Nature defined
Romans 3
9 What then? Are we better than they? Not at all; for we have already charged that both Jews and Greeks are
all under sin; 10 as it is written,
“There is
none righteous, not even one;
11 There is none who understands,
There is
none who seeks for God;
12
All have turned aside, together they have become useless;
There is none who does good,
There is not even one.”
13 “Their throat is an open grave,
With
their tongues they keep deceiving,”
“The poison of asps is under their lips”;
14 “Whose mouth is full of cursing and bitterness”;
15 “
Their feet are swift to shed blood,
16 Destruction and misery are in their paths,
17 And the path of peace they have not known.”
18 “
There is no fear of God before their eyes.”
It is the condemned "in harmony with Satan" state of man's nature from birth.
