I'm always nice to everyone - until they show their true colors and the colors just... don't work for me. That's when "my attitude depends on who you are," good and/or bad. Too many people mistreat nice people and suck up to those who mistreat them.
We serve a supernatural God! He can do what medicine cannot do. He is not limited by your education, your background, the family you came from. He’s not moved by the things people have spoken over you. He’s not up in heaven all frantic, trying to figure out how to get you to your destiny. He knows the end from the beginning. He already has solutions to problems you’ve not even had. He is all powerful and all knowing.
