Psalm 79:12 Pay back into the laps of our neighbours seven times the contempt they have hurled at you, Lord.
What is your attitude toward people who have chosen not to believe in Christ? Do you call for them to be burned as chaff?
Jesus taught us to not be this way because He saw the divisions this brought into our lives.
God wanted us to be separate from non-believers to give us a chance at having hope; Jesus came to give us physical and spiritual hope, turning these divisions into something very different for us.
