Satan always want to get your imagination corrupted, he knows that's the only way he can seat behind the wheel of your life. You must know that, as a man, your mind is the controlling force of your life. Imagination is powerful, learn to use it for your advantage.

Meditation and imagination are one and the same in Greek, "melatao". So meditation or imagination is the process of formation of new images that changes our world. I said sometimes ago that "image is everything", that's why media are very powerful in our world. What you see can change your life forever, the question is, what are you seeing?
