As I've been insisting, righteousness is not merely imputed to man; it's imparted to him.
But you haven't shown that from the Bible.
That's why one begins to behave-or certainly should-more righteously.
You have touched on the key: "should". That's why there are many commands for righteous behavior.
And we are intended to grow in that righteouness, in that love, as we 'grow also in the grace and knowledge of our Lord Jesus Christ' (2 Pet 3:18).
Yes, "intended". Now, the only way to grow in that righteousness is by being filled with the Spirit.
So again, can you explain HOW to be filled with the Spirit?
And the verse before that warns that we can lose our secure status:
"Therefore, dear friends, since you have been forewarned, be on your guard so that you may not be carried away by the error of the lawless and fall from your secure position."
Yes, not a real secure position.
If you believe the verse actually means what you are suggesting, then Jesus was lying in John 10:28. He said recipients of eternal life shall NEVER PERISH.
English Standard Version
You therefore, beloved, knowing this beforehand, take care that you are not carried away with the error of lawless people and lose your own stability.
King James Bible
Ye therefore, beloved, seeing ye know
these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
New American Standard Bible
You therefore, beloved, knowing this beforehand, be on your guard so that you are not carried away by the error of unscrupulous people and lose your own firm commitment,
Holman Christian Standard Bible
Therefore, dear friends, since you know this in advance, be on your guard, so that you are not led away by the error of lawless people and fall from your own stability.
American Standard Version
Ye therefore, beloved, knowing these things beforehand, beware lest, being carried away with the error of the wicked, ye fall from your own stedfastness.
Aramaic Bible in Plain English
You therefore, beloved, as you have known beforehand, guard your souls, lest you go after the deception of those who are without The Law and you fall from your own stability.
Weymouth New Testament
You, therefore, dear friends, having been warned beforehand, must continually be on your guard so as not to be led astray by the false teaching of immoral men nor fall from your own stedfastness.
World English Bible
You therefore, beloved, knowing these things beforehand, beware, lest being carried away with the error of the wicked, you fall from your own steadfastness.
Young's Literal Translation
Ye, then, beloved, knowing before, take heed, lest, together with the error of the impious being led away, ye may fall from your own stedfastness,
None of these translations indicate any potential of loss of salvation.
Here is the Greek word and meaning:
stérigmos: a setting firmly, steadfastness
Original Word: στηριγμός, οῦ, ὁ
Part of Speech: Noun, Masculine
Transliteration: stérigmos
Phonetic Spelling: (stay-rig-mos')
Definition: a setting firmly, steadfastness
Usage: firmness, steadfastness.
The point is that those who are carried away by the error of the wicked will LOSE THEIR OWN STABILITY, FIRMNESS, STEADFASTNESS.
