In lesson 8 we are shown that we see only the past, because our mind is preoccupied with past thoughts. Our mind is busy, loud, fast paced, quick thinking, and appears as images, pictures and memories; all of which are our perception of the past. They are not our true thoughts. God speaks to us all the time, but we do not hear BECAUSE we are preoccupied with our own voice. In this lesson Jesus reminds us that our mind is really blank. Thus we need mind training to remember our real thoughts.
(I am happy to share Britneys video on this lesson with you. But as the sound is weak, I suggest you use your earphones – Enjoy!)
