Fear and worry come from imaginings about the future. Peace and Perfection come from resting completely in The Present. The Present with the past or future. Without anger or guilt about the past, or fear or worry about the future, only the Peace and Perfection of The Present will remain. We are creating an imperfect past and future in our minds, while God has created The Perfect Present in Reality.
Reality is Now.
Reality is Perfect. We can so completely separate ourselves from The Present Perfection of Reality with something as unreal as an angry or fear-full thought. In The Present is the present of Perfect Peace. But they can, and most certainly do, affect the way we see and experience this perfection. We need only stop impressing upon it our thoughts about the past and future in order to see this ever present Perfection.
