There have been times when I wasn't a "good Christian" - I lost my temper, said something I shouldn't. But Scripture tells us that pastors are going to be judged more strictly than the rest of us.
Here is a tough question: At what point do we not judge because we're told that by the same measure we judge, we will also be judged - as opposed to turning away from pastors who are itching ears?
Matthew 7 goes on to say vs 5 "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."
John 7:24 "Do not judge by appearances, but judge with right judgment.”
Specifically, other believers - 1 Cor 5:12-13 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. “Purge the evil person from among you.”
Judgement often is taken out of context (I'm not talking about your post - I mean in general). People are so afraid to judge, but as Christians we are to judge with "right judgment", not as hypocrites. There's a difference between rightly judging, calling out bad behavior - and being judgmental or "holier than thou". Being judgmental is always wrong.
There are lots of verses showing how we (believers) are to call out sin, not condone it -
Eph 5:11 Take no part in the unfruitful works of darkness, but instead expose them.
1 Tim 5:20 As for those who persist in sin, rebuke them in the presence of all, so that the rest may stand in fear.
Paul reminded the church in Galatia that he rebuked Peter in Antioch (Galatians 2)
Keeping in mind ~
"Brothers, if anyone is caught in any transgression, you who are spiritual should restore him in a spirit of gentleness. Keep watch on yourself, lest you too be tempted." Gal 6:1
Joel Osteen, saved? Probably. I don't know. I do know he doesn't preach the whole council of God and he'll be held accountable for that.
I'm also very skeptical of those who claim Christ yet don't preach/teach His word rightly divided. More and more these days people who consider themselves Christian aren't what they claim to be. Deception abounds, discernment is a requirement.
