Taking on the issue of "spectator Christianity" in his Book Infusion, Jack Redmond writes to a Church that has been passive in reaching out to a sinful and dying world. He challenges believers to learn to receive what God gives, forgiveness, authority, love to grow in these things and to shift the focus from self toward helping others. The title of the book Infusion means to cause to penetrate; instill; to fill or to be filled with something. The author makes the point that our world is in a desperate need of an infusion of Jesus Christ.
