Remember the smell of crayons you took out of your school desk years ago? Remember your first "big" box of crayons? Forty-eight? Sixty-four? You imagined all you could make and dream up with a palate like that. Your artistic output would be nearly limitless.
God wants to do a limitless variety of things through His church on earth. It takes every kind of person and nearly limitless combinations of skills, personalities, experiences and gifts to pull off what God wants to do through us. That means whatever "color" you are, there's a place in the box for you.
