It is Christian to judge. Yet God does not want us to judge.~
So, I was chillin and feelin God's Love in me the other morning and thoughts were coming to me from, I believe, The Holy Spirit or God, and it was ultra clear in that moment that judgment of all kinds is wrong.
I have always grappled with judgment. I've never liked to judge nor condemn others, preferring to spend my time asking, "Why?" rather than, "You shouldn't." So in bible study in the Fall, I finally tracked down the answer to when one is allowed by God, according to the Bible, to judge or rebuke. That is when the person is another believer. The Bible says not to rebuke or judge when the person is not a believer, because you are just wasting your time. Interestingly as well, the Bible says not to fraternize with believers who are swindlers, thieves, idolaters, etc., but you can fraternize with non-believers who are, evidently? So, it's like once we call ourselves a Christian, we collectively become degraded somewhat, because we become judgers of our fellow brother. Yet we are admonished to not ever say one ill word of fellow believers, except evidently for rebuking them. Along these lines, once a native of somewhere hears of Christ, Christians surmise that if they then do not accept Jesus as the savior, they will then go to hell.
In bible study when I'd question my fellow bible study girlfriends, they were all over judging each other to keep us on the straight and narrow; indeed, it's a well-known and espoused Christian policy that you will be reigned in by your fellow Christian brethren, and that that is a benefit to being a Christian.
I think this is where Christians become the self-righteous hypocrites that they are.
I know from grappling with it myself for even just a few months, that judging my fellow sisters/brothers took me further away from God's love, though it tied me closer to the Christian faith, and Jesus' supposed words. Having now abandoned judgment and rebuking I've already felt freer in my love for others and for myself as well~! I KNOW that God does not want us to rebuke each other or to judge each other.
So the Bible is wrong on this point.
Was Jesus wrong, or was he interpreted inaccurately? Or was he used by others down the line for their own agenda? I'll never know unless God reveals it to me. I haven't actually asked yet. Maybe I will.
Anyway, yeah. I'm pretty sure judging others is never right. All we have control over is ourselves. And we need to each have a direct line to God and God only. Everything beyond that is love-lagnappe.

Only God should be the judger and rebuker. [This might be different for raising our children. I'm not really sure.]
