From: The Marvelous Way God Works with Us Episode 8

Question:
....Does the Holy Spirit turn our imagination into a real Kingdom experience?

Graham:

In Christ the Holy Spirit is often the Source of our imagination because His role is to take the things of God and reveal them to us.

Imagination is an inner vision that leads to perception that our natural mind could not conceive.

Imagination is creative thinking. It is the place where dreaming takes us beyond what we can ask or even think. Ephesians 3:20.
