In Blood Works, Dr. Horace E. Smith M.D. explains the power of common grace and special grace to prompt true worship and transform our relationships with God and the people around us. For Christians, understanding the natural working of blood fills us with wonder and insights. With incredible precision, the cells in our circulatory system provide nourishment, protection, and healing to every cell throughout our bodies. These provisions are part of the common grace all of us enjoy. But blood has even greater significance for believers. Throughout the Bible, from Genesis to Revelation, we find that the blood of the Savior, sacrificed for us, is the only source of special grace—the love, forgiveness, and acceptance of God.
