Separation from the world's religion?

Spurgeon, "Light, Natural and Spiritual" #660.

As soon as the Lord gives to any
believer spiritual light, he begins to
separate himself from the darkness.

The world's religion used to satisfy him. If there
was a pretty looking building, and a good looking
minister who could put his words together well,
and garnish the altar finely, the child of darkness
did not care what he heard; whether the gospel
was preached or not.

But so soon as he receives spiritual light, he cries,
"All this is nothing to me, I need light and truth,
and I cannot go to hear anything but the gospel."

He separates himself from the world's religion,

finds out where Christ is preached, and goes there.
