I agree, however, I am always a fruit inspector....the fruits of the Holy Spirit in one's life, or the lack of them, tells me a lot! God calls us to be "fruit inspectors", and I'm not gonna apologize for being one of them!
You will never truly understand the struggles of another person. Remember to realize how hard your own struggles are for you, the other guy feels the same way about his life. We are all trying to make our way in this world so make it easy on everyone and don't judge
