meh, it's not for me to judge on matters that belong in Jesus' court, of the heart.
All I need to judge is what people say or do that affect me, or others in a
fashion that is negative according to what is good as described by Jesus.
Making the distinction of whose realm the judgment falls can be tough sometimes,
and is why Jesus told his disciples at the time, not to judge at all. He was
in both worlds at the time, so they didn't need to.
Now he's in mans heart, so a believer has to turn inward to him on it,
so what is perceived as a persons judgment maybe not be even what that
person wants.
That's kinda the short of it on judgment, and I don't like typing that much,
but the bible expounds on it quite a bit.
So if a Christian has doubt on a judgment of another, don't judge that situation at all.
If one misjudges, and realizes it later, then it has to be made right, and or asked forgiveness for it.
