We judge all the time. Everyone does. The difference is we do not judge in the sense that we dispense a sentence.
I think this is one of the most misquoted and misused scriptures in the Bible, besides money being the root of all evil, when it is actually “the love of money.”
If one of your children was hanging around with a drug user, I’d bet you’d judge real quick.
It is God's role to decide who is a “real” Christian and who is not. You put your soul in jeopardy when you judge the righteousness of others. The mote in another's eye and all that. You are also wrong about the eye of the needle. Every dollar that you have above what you need is a black mark on your soul as long as someone in the world has a dollar less than they need.
