This book is for you--the normal, unimpressive, everyday person, young or old, male or female--because Jesus means to carry out his mission of filling the world with his presence through you. You are meant to do this.
The mission of Jesus is yours to participate in. It has always been God's intention to choose normal, everyday people, and to show his amazing power and glory through them. He's not looking for the most impressive person because he already is that person.
