However, the lost preachers as featured in the link about set about to establish their own righteousness. Today it's refered to as "virtue signaling", which is " look how virtuous WE ARE, because we provide a safe space of acceptance to the LGBTPEDO community. You Bible believers are HATERS so we hate YOU...Blah, blah, blah.!"
Love tells hateful preachers who is allowed to preach what
They reject the sacrifice of Christ as an inclusive afterthought....after their veneer of "love."
There are even serious sins that believers who are destined for heaven commit. Jesus addressed the sin of the church of Pergamos as accepting into their assembly those who teach the doctrine of Balaam, etc. He said that He hates that and He warned them to get rid of such scoundrels.
One more example of a saved believer who was guilty of serious sins was Lot in 2 Peter.
"And turning the cities of Sodom and Gomorrha into ashes condemned
them with an overthrow, making
them an ensample unto those that after should live ungodly;
7And delivered just Lot, vexed with the filthy conversation of the wicked: 8(For that righteous man dwelling among them, in seeing and hearing, vexed
his righteous soul from day to day with
their unlawful deeds."
We know that Sodom and Gomorrah were full of wicked reprobates that rejected the Lord so the Lord considered them rejects.
He nevertheless spared Lot and offered to do so for his entire family.
Lot was considered just and a righteousness man, not because he was an example of great morality, but because he believed the LORD and was saved eternally.
We could go on and on but your point is well taken and Biblical because you point to the Lord as the reason rather than the virtue signaling self righteousness as the reason. He trusted the LORD, the righteous one and it was accounted unto him for righteousness as was said of his uncle.
