Be careful when you judge others. It’s so easy to look at other’s actions as wrong and not even see what we ourselves are doing wrong. Sometimes God is working in our heart to change a behavior, yet we see others do it and seem to “get away with it”. This is between them and God, not me, them, and God. Take your struggles to him, but remember he may not respond… it isn’t your concern.
When my ex left and I first discovered he was actually having an affair with my best friend. I struggled with this. I wanted him to be convicted of his errors and come home. I wanted the whole nightmare fixed. I so clearly saw the sin, but my ex and best friend didn’t. I would argue and argue with God about how it was wrong, how it was unfair, etc. What I only got was how to fix me. How to work on me. What happened with them wasn’t my concern. Yes, he listened to my rants, but it wasn’t my issue to fix. God instead showed me where I have gone wrong in relationships, and how I too have hurt others. He helped me fix that.
Be self aware of your own problems, issues, struggles, sins. Work on those with God. Don’t complain about others problems. We all have them, we all have areas to work on.
