Your imagination is like a canvas. You can paint on it any kind of picture you choose through your thoughts, attitudes, and what you decide to focus on. Don't let doubt or fear paint on your canvas. Don't let the "impossible" or "can't be done" thoughts blur the colors on your canvas.
The eye is the lamp of the body; so then if your eye is clear, your whole body will be full of light. But if your eye is bad, your whole body will be full of darkness. Matthew 6:22-23 NASB
