Ez 3:20 Again, When a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumblingblock before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.
Isa 8:14 And he shall be for a sanctuary; but for a stone of stumbling and for a rock of offence to both the houses of Israel, for a gin and for a snare to the inhabitants of Jerusalem.
1Pe 2:8 And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
As ezekiel says, their qualifications for JUDGING, they were the righteous, which when they TURN FROM IT, are DISQUALIFIED UNTO LIFE. He shall die in his sin.
The verses you quote are very good gospel verses. All people fall short. None are righteous. In the light of the gospel, all are disqualified unto life and all would die in their sin, except for Yeshua.
So, these verses do not apply to judges, as it is not a requirement in the Mosaic covenant that judges be born again.
They had turned from their righteousness long before they set in the Sanhedrin to put him to death.
They had turned from their righteousness from John's baptism on.
Eze 3:20 Again, When a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumblingblock before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.
Ez 18: 26 When a righteous man turneth away from his righteousness, and committeth iniquity, and dieth in them; for his iniquity that he hath done shall he die.
27 Again, when the wicked man turneth away from his wickedness that he hath committed, and doeth that which is lawful and right, he shall save his soul alive.
28 Because he considereth, and turneth away from all his transgressions that he hath committed, he shall surely live, he shall not die.
Eze 33:17 Yet the children of thy people say, The way of the Lord is not equal: but as for them, their way is not equal.
Eze 33:20 Yet ye say, The way of the Lord is not equal. O ye house of Israel, I will judge you every one after his ways.
Mt 9:10 And it came to pass, as Jesus sat at meat in the house, behold, many publicans and sinners came and sat down with him and his disciples.
Mt 9:11 And when the Pharisees saw it, they said unto his disciples, Why eateth your Master with publicans and sinners?
Mt 11:19 The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.
Lu 7:29 And all the people that heard him, and the publicans, justified God, being baptized with the baptism of John.
30 But the Pharisees and lawyers rejected the counsel of God against themselves, being not baptized of him.
The gentiles turning to God, from their SIN.... as Ezekiel says....
Ac 11:18 When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.
Consider Ezekiel QNTS
Joh 15:22 If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin.
Joh 15:24 If I had not done among them the works which none other man did, they had not had sin: but now have they both seen and hated both me and my Father.
Again, consider that the New Covenant is different then the Mosaic covenant. In the Mosaic covenant, eternal salvation is not offered. So, in the view of eternal salvation, all of their righteous acts (which would be acts of keeping the law), do not earn the righteousness of Messiah. All of that righteousness is their own works and does not measure up.
So, it is the righteousness of Messiah, and not our own works of the law, which offers eternal salvation.
So, you have David, who was righteous by faith, even though he sinned according to the Mosaic covenant.
And we know the Moses was not allowed to enter the promised land due to his disobedience, yet by faith Moses was righteous. Moses committed murder, yet was righteous by faith. So, it is not by works, but by faith. And faith can occur when a person is young like David, or old like Moses.
I do not understand why you want to show the unrighteousness of the judges, as scripture says our own righteousness is as filthy rags. So all are unrighteous in light of eternal life and salvation. The point is Yeshua. And Yeshua said that no one could take His life, but that He chose to lay it down for the sheep.
Take Mother Theresa, she did many good acts, but those acts are only her own righteousness, and her own righteousness does not earn eternal salvation, so Mother Theresa, for all that was good she did, was still a sinner, bound for hell. Her own righteousness is summed up as filthy rags, according to scripture, as they are not sufficient to earn eternal salvation. If Mother Theresa never came to trust in the saving work of Yeshua, she would be with the judges who also never came to trust in the saving work of Yeshua. And if Mother Theresa trusted in Jesus completed work, and some of the judges trusted in Jesus completed work (which Easy said there is evidence they did), then they are eternally saved, not based on any good or bad work they did but based on the righteousness of Messiah.
So in light of eternal salvation, we can not boast on anything good we have done, and since Yeshua died for sin, we can not exclude anyone from the possibility of eternal salvation, because of their sins, because eternal salvation by the righteousness of Yeshua, is by grace thru faith.
