Make room in your heart for people as they are, not as you wish they were. Wouldn’t it be nice if everyone would measure up to our expectations? But we’re all human beings and we all fail.
You work every day under the supervision of God. Do what you do because God has you there. Live at peace. The war in your own heart is over and you don’t need to worry with your focus on God.
If you work in Christian ministry it is work. As a boss to others don’t boss people around, but lead them. Be gentle when giving criticism. Be courteous.
