Let compassion guide you. We ought to love those God brings into our lives. It isn't our job to shake our fingers at them; be law enforcers with others; tell others where they are wrong. This isn't our job. No one needs this. They get it from everyone else in their lives. God will deal with people inwardly -- where it is most effective and where lasting changes can happen.
We are to show others love, compassion, kindness, gentleness, patience.
Anyone can be harsh and judgmental. That's easy to do.
Showing real compassion and kindness and humility toward someone you don't agree with is hard. Showing them these traits when you might think they are totally wrong, even living wrong, is what God has called us to do. Do this sacrificially. Do this today.
