"Let any amongst you who are without sin cast the first stone."
I love how liberals/libertarians who have never touched a Bible know that passage, yet they stop short of the point where Jesus told the woman, "GO AND SIN NO MORE!"
Jesus had to power to forgive the woman, because Jesus is Almighty LORD of the Universe.
Jesus never called for an end to man's law so that man can do what is right in his own eyes.
The passage on Judging is prohibiting hypocracy, people judging people while doing the same things in their own private lives. That is what the people the passage was intended for where doing. Biblical Passages must be read in Context.
In Context the Biblical passages on this issue are very clear:
"Thou shalt not lie with mankind, as with womankind: it [is] abomination." (KJV) Leviticus 18:22
"If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood [shall be] upon them."(KJV) Leviticus 20:13
"Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals, nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God." 1 Corinthians 6:9-10 (NASB)
"There shall be no whore of the daughters of Israel, nor a sodomite of the sons of Israel." (KJV) Deuteronomy 23:17
There are more like the above, but you get the point.
For we know Him who said, "Vengeance is Mine, I will repay," says the Lord. And again, "The LORD will judge His people." It is a fearful thing to fall into the hands of the living God. Hebrews 10:30-31 NKJV
I rejoice when I reflect that God is Just, and that his Justice cannot sleep forever.
