Sin is birthed in the mind. Even if it never leaves the mind, it still exists.
Whoever practices righteousness has been born of God.
The regular practice of righteousness does not mean sinless perfection.
No one is perfectly righteous.
And this is an openly false statement, trying to mesh 'perfectly righteous' with 'perfectly sinless'. Perfectly righteous
is the commandment to be righteous, even as He is righteous: to be wholly living by His faith with
all the heart:
Ye are witnesses, and God also, how holily and justly and unblameably we behaved ourselves among you that believe.
This is Scriptural definition of living perfectly righteous:
And besought him that they might only touch the hem of his garment: and as many as touched were made perfectly whole.
It is living perfectly righteously, because of a heart made perfect by the power of God:
I will behave myself wisely in a perfect way. O when wilt thou come unto me? I will walk within my house with a perfect heart.
We are to be righteous even as He is righteous, and He is
perfectly righteous altogether.
Scripture does not play semantics of 'perfectly' righteous, because God is not speaking to children playing word games, but to adults who know what He says and know He means exactly what He says.
That's why we need Christ's righteousness applied to our account.
His righteousness is not 'applied' over any 'account' of sins, even as His blood does not only 'cover' and 'hide' any soul's ongoing sins.
Your statement is the learned stuff of unconditional salvation. No Scripture speaks of Jesus' righteousness and blood as being 'applied' to anything, much less over a soul's sinful 'account'. That is garbled baby-talk used by some to justify being perpetually double minded, and so soothe and sear their conscience unto the end.
The only thing 'applied' in Christianity of Scripture is Christians
applying their hearts to God, His knowledge, and His righteousness.
Whoever practices righteousness has been born of God.
And so, I see now why Christians like to use the word 'practise' so much, rather than 'do': it's a luring cover for partial Christianity communing with partial sins of the world.
Christian saints living blamelessly in this life are
doing the righteousness of Christ, not
'practicing' at it, and failing at it time and again in ongoing unrighteousness and trespasses against God.
Them that obey Him shall obtain His eternal salvation, not them that 'practise at' obeying Him from time to time and so also practise at disobeying Him from time to time.
Practicing Christians are them doing His righteousness. Them doing both righteousness and unrighteousness are just practising at it, but never doing it. They are practising at repenting, while never having repented.
The regular practice of righteousness does not mean sinless perfection.
The continued doing of His righteousness, even as He is righteous, is the commandment of God to His people, and sinless perfection will then be obtained in the resurrection by all such who do so and obey Him in all things.
Double minded Christians are only 'practising at it', and they are commanded like all sinners everywhere to repent and to purify their hearts and cleanse their hands from their ongoing sins and trespasses:
Submit yourselves therefore to God. Resist the devil, and he will flee from you.
Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded.
1. While it is true, that there is difference between committing a sin and committing to sin unto the end, it becomes a slippery slope to justify sin: to not see our sins so devilish as that of unbelievers.
2. The difference between the Christian saint and Christian hypocrite is twofold:
The saint knows he or she
can still sin and disobey God, but only
if he or she does not endure temptation and falls in defeat of the devil.
The hypocrite believes he or she
will sin, so that it is only matter of
when, not if. Also, they do not see their sins as evil as that of the world and of the devil, because they like to think their own sins are not seen by God in the same righteous light of judgment: They accuse God of having respect toward their persons with sins, and no respect towards other persons with sins.
The Christian saint takes Scripture seriously, and so with the mind of Christ sees all things in the light of Scriptural truth, but not the hypocrite who speaks things that sound great to themselves, yet are blasphemy against the Word of God:
And there was given unto him a mouth speaking great things and blasphemies.
When teaching doctrine of Christ, we must use only the words of Scripture to do so, and cut off all the other words, expressions, and ideas of the carnal minded.
