Gifts From God, Magic From The Devil.

Bill Jackson is a warrior, given gifts from God (1 Corinthians 12). He wears the armour of God. But now he's old, in the dusk of his life, racked with guilt and remorse. But when his relatives are murdered he faces his greatest challenge yet.
Into his life comes Tommy Jackson, eighteen years old, another warrior, an African-American from New York, but confused about these gifts he's been given. They team up and find themselves being sacrificed to the Devil.
