LW and his like can only thump limited selections of the bible to do it convincingly.

For example, if you read the entirety of the Sermon on the Mount in Matthew 5-7, which is a thorough description on the ethics of his kingdom and those who enter his kingdom, he wraps it all up at the end by reminding his listeners to not misuse these teachings as a way to judge others and exalt oneself -- do not judge lest you be judged, take the log out of your own eye before the speck in your brother's eye, etc.

Oh and the most misunderstood saying: "do not cast your pearls before swine, nor give what is holy to dogs, lest they trample it underfoot turn around and attack you." This is called literary irony -- Jesus is saying if YOU assume that you are the bearer of priceless pearls of wisdom and holiness, and those other sinners are not even human they're swine and dogs, then don't be shocked when others sense your condescending attitude, they'll reject your "pearls" of wisdom and attack you mercilessly. You'll get what you deserve in your hypocritical self-righteous hubris.

Jesus knew how many of his self proclaimed followers would publicly speak and behave, and called it out way ahead of time.
