Judge not, least you be judged.
Actually, that "value" is one of THE most misquoted verses in the Bible. Obviously, God's judgement alone determines ones eternal destiny, however does that mean we are meant to know nothing for sure, since all knowledge depends on making inferences and judgments?
To take an extreme example: Was Hitler a Christian? He was baptized (so what?) but repeatedly, in private usually, indicated he was an atheist, and never made a confession of Christ to his dying day.....AND of course never repented from his monstrous crimes and murders of tens of millions.... So as far as humans can know, Hitler was certainly not a Christian. In saying that am I "judging" in a way Jesus condemned? Certainly not! Just speaking the obvious.
Here's what Jesus said about judgment IN CONTEXT:
“Judge not, that you be not judged. For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you. Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother's eye." (Matthew 7:1-6)
Jesus was condemning judgmentalism....that is self-righteous people LOOKING for small faults in others, while ignoring much bigger faults in themselves. Clearly He was speaking to the motivation for fault-finding, NOT saying we can never make moral judgments about the souls and the behavior of others....rather before doing so, we better take a good look at ourselves--and make sure we're clear, before helping (emphasis on HELPING) others take specks from their own eyes.
Obviously with M.L. King, and all the dead, we cannot help them correct themselves, however, given the total hero-worship given him--and inaccurate portrayals, especially in the black community, that he could do no wrong--I think it is very useful to make an accurate assessment of the man, and his Christian testimony given, and especially, since it is politically incorrect to do so.
I have read evangelical Christian leaders (especially British ones, interestingly) lauding the great Christian faith that moved M.L. King to push for desegregation and social reforms...calling him in essence a great evangelical Christian. However the evidence that I've seen and read says otherwise.
Like a Jefferson, or a Thomas Paine, M.L. King surely did some great things--and was used by God to bring justice to America--however he was not a Christian, and we do harm by pretending that he was. Here's the link referred to above, and left out, of a paper by an African American woman, proving by M.L. King's own words, his beliefs about Jesus:
well how about this...
Let he who is without sin cast the first stone.
