What is the soul power or natural energy?
It is simply this, what you can do, what you are yourself, what you have from nature.
The power of the soul is present with us all.
Those who have been taught of the Lord repudiate that principle as a life principle: they refuse to live by it; they will not let it reign; they will not allow it to be the power-spring of the work of God.
But those who have not been taught of God rely upon it; they utilize it; they think it is the power.
