"Take heed, and beware of covetousness." If love of the world or covetousness... slips into the heart it checks the power of Christ over the soul and conscience, and eats out the practical life of the Christian, and his soul is withered, withered, withered... This covetous care about earthly things is so subtle that while there is nothing on which to lay the hand, the practical power of christian life in the soul is gone.
