Yes, in the beginning of life in the flesh for mankind this is true.
Satan has no flesh body. It's an adverse antiChrist spirit
Genesis 3:15 "And I will put enmity between thee and the woman], and between thy seed and her Seed; It shall bruise thy head, and thou shalt bruise His heel.
But the verses in Ezekiel, Isaiah, Job, etc before that make it clear he was perfect -without blemish until iniquity was found in him.
Obviously not perfect by the time of the garden event.
And I see you continue to cherry pick certain verses leaving out the rest of the parable. Only a portion had the seed stolen from them. Some of it fell on good ground therefore not stolen.
I've always said as Jesus taught us, that man shall live by every word of God. Not just the ones we like, which is what you're doing. Matt. 4:4, Luke 4:4, Deut. 8:3
No, that is not my claim. Only that at the present time it's much easier for mature Christians to resist his spirit When he's here disguised as that angel of light that's when we need to have the full gospel armor on and in place if one is here during that time period.
Point being the tempter and his own operate within mankind.
You need to know the difference between living in sin/habitual sin and missing the mark/falling short. No one is without sin but there is a difference.
You're merely looking at the external act of sin. IF the tempter operates within, then the worst sinner who has been involved within inserting that temptation, and it really doesn't matter much from that observation. Every sin is technically within, because of that bad actor, not because of your external act of sin, or lack thereof.
You can subscribe to the fantasy that your sin is better than the other people's because it's not overt, but your less than overt sin really has nothing to do with sin and Satan, if you follow the logic.
Satan isn't any less the sinner in anyone.
Case in point, you pointed out 1st John 3:8 but fail to see verse 7 for what it is and we can tie both together so we can see the difference.
I John 3:7 "Little children, let no man deceive you: he that doeth righteousness is righteous, even as He is righteous."
I don't ascribe any sin to the person, just so you know, per Paul, 2 Cor. 5:19
That does NOT mean sin's are not counted. They are counted against devils.
I John 3:8 "He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that He might destroy the works of the devil."
John is making the distinction but you cannot.
You only want one side of the equation but not the other is all. Why would you have any problem condemning the tempter in you or anyone else???
In fact why don't you see that condition in others to begin with???
Why don't you admit you're tempted internally by the tempter and then this one sided good word only game might stop.
Believe me, no one will be able to drag Satan along with him when they're standing in Judgment.
You mean like this?:
Zech. 3:1-3
And he shewed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him.
And the Lord said unto Satan, The Lord rebuke thee, O Satan; even the Lord that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?
Now Joshua was clothed with filthy garments, and stood before the angel.
No Satan in the picture? Guess again.
Contrary to what you want to believe Jesus showed us all that Satan and devils were in mankind, period.
That hasn't changed. All have sin. Sin is of the devil. Paul himself had a devil in his own flesh, 2 Cor. 12:7 and had temptations in his flesh and mind. Romans 7:7-13, Gal. 4:14
So, yes, it's never just you or I or anyone else involved in these questions. It's us and the adversary and or his own
Who's making excuses? Show me where I provided any excuses? He's a dead man walking so to speak bound for the Lake of Fire.
I may have mistaken you for a Christian universalist, which I am, who actually loves our neighbors as ourselves.
My apologies.
