The truth is peace comes from God. I can’t have peace with God until I have claimed responsibility for my will. But after we claim responsibility we have to surrender our lives to Jesus.
Before you can have real peace with others you have to find peace with God. There is a lot made about people finding God and making peace with God but I can tell you it’s not something that you get to do at the end of your life. It’s something you need to do as you grow in your life in Jesus.
"Great peace have they who love God's law, and nothing can make them stumble."
