The disturbance you are experiencing reveals a battle over the control of your mind. You are made of body, mind, and spirit. What you describe, relentless attacks on body and mind, robbing your sleep, is exactly what Scripture calls the mind of the flesh. When the body’s needs and fears are allowed to rule, the mind becomes consumed with what it can see, feel, and dread. The result is death, restlessness, depletion, a troubled consciousness.
Yet the real you is not this tired body. The real you is spirit. The body is merely an instrument, a temporary tent. It groans, it suffers the pull of corruption, and it clamors for control. That is why there is a war inside: the spirit lusts against the flesh, and the flesh against the spirit. The enemy exploits this weakness, hurling fiery darts at your mind when you are at your most defenseless, in the quiet of the night. His aim is to keep your mind fixed on the physical and the fearful, so that your spirit remains stifled and your peace is shattered.
The shield against these attacks is the truth of God’s Word. Just as Jesus met every assault in the wilderness with “It is written,” you must counter the lies with the truth. When the mind is stampeded by anxiety about sleep or physical sensations, refuse to let it run unchecked. Instead, set your mind on the things of the Spirit. Present your body to God as a living sacrifice, even in the act of lying down, and be transformed by the renewing of your mind. The command is not to let sin reign in your mortal body, and that includes the sin of allowing dread to dominate your thoughts.
Your spirit, united with Christ, has authority. You are not a body with a soul; you are a spirit with a soul, living in a body. Bid your spirit to take its place uppermost, filled with the knowledge of God. Pray, “Father, preserve my whole spirit, soul, and body blameless.” Ask Him to keep your mind stayed on Him, so that in the dark hours, your consciousness rests in His presence. The truth that He is your shield and buckler is not a feeling, it is a fact to be wielded.
Take comfort in the temporary nature of this struggle. This old body, with its need for sleep and its vulnerability to attack, is not your permanent home. It is perishing. The day is coming when you will be absent from this tent and present with the Lord, clothed in a body that needs no rest, a building of God eternal in the heavens. That hope is not an escape from the present battle; it is the anchor for your soul while the battle rages. In the meantime, whether you wake or sleep, you are living together with Him. Trust His truth to be the guard over your mind tonight and every night, until the morning breaks and the shadows flee away.
