Salvation cannot come without revelation. Men of the present time testify of heaven and hell, and have never seen either; and I will say that no man knows these things without this.
There is no such thing as immaterial matter. All spirit is matter, but is more fine or pure, and can only be discerned by purer eyes. We cannot see it, but when our bodies are purified, we shall see that it is all matter.
We may come to Jesus and ask Him; He will know all about it; if He comes to a little child, he will adapt himself to the language and capacity of a little child.
