Most people agree that we should repent from our sins and shortcomings and they never include repenting of their own righteousness. Our own righteousness, unless repented of, will hinder our entrance into the Kingdom of God because we cannot enter the Kingdom of God with our righteousness. We cannot enter The Kingdom of God with Christ's righteousness and our own mixed to any degree.
Repenting of our unrighteousness, is how we turn from doing our own righteousness. Man's righteousness is doing both good deeds and bad intermixed together.
For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
God's righteousness is doing good and right with Him
at all times.
Blessed are they that keep judgment, and he that is doing righteousness at all times.
While you make a good point about how our righteousness does not fulfill the righteousness of God, there is no Bible commandment by God to 'repent' of our righteousness.
God's commanded repentance is of our sins, trespasses, transgressions, iniquity, and unrighteousness.
'Repenting' of doing our own righteousness,
is de facto by repenting of doing our own sinning and trespasses. When we are dead to our own past sinning for Jesus' sake, then all that remains is His righteousness that we now do through Him.
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. And all things are of God,
Like purifying gold from all dross of uncleanness, the gold is become pure.
That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
Our righteousness is like filthy menstrual rags.
Correct. There are two ways for our deeds to be our own righteousness, and not God's true holiness.
By doing outward righteousness with an unclean heart of lust.
Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
By doing deeds with good will at times, but also doing evil deeds willingly.
For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
Once we commit any iniquity against God, then we are now doing our own righteousness of both good and evil. We are no more doing God's righteousness, which is at all times.
When I shall say to the righteous, that he shall surely live; if he trust to his own righteousness, and commit iniquity, all his righteousnesses shall not be remembered; but for his iniquity that he hath committed, he shall die for it.
Trusting in our righteousness is by trusting our past righteousness to justify us with God, even when turning to do iniquity.
It's the old religious saw of good deeds outweighing the bad. Man's judgment of man's own righteousness is of doing more good than evil.
God's judgment is of His righteousness is of always doing good at present. God judges our works being done now, not in the past.
Little children, let no man deceive you: he that is doing righteousness is righteous, even as he is righteous.
Beloved, follow not that which is evil, but that which is good. He that is gooding is of God: but he that is doing evil hath not seen God.
Only those doing righteousness are righteous as the Lord is, and if we turn to doing unrighteousness works of the flesh, then all our past is forgotten as having never known God at all.
Therefore, only those doing righteousness at the end, are judged as His righteous sons forever.
Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended.
Throw something like that in a basket of fresh laundry and you will redo the entire load.
Exactly. It's not those doing more good than bad, that are righteous with God, but only those doing His will always.
And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him.
If you spend time with people concerned with their own righteousness, you will not find pleasant people.
True. Their righteousness becomes their own standard to judge others by, as well as becoming their own justification, while continuing to do unrighteousness.
