The fear that grips your heart is understandable, but consider what great comfort the Apostle gives. "We are more than conquerors," he says. Not merely conquerors, but more so, winning victory with ease, without toil and labor, because it is God who strives together with us. When you cry out for a witch to be bound, you imagine a terrible power arrayed against you, yet the truth is far different. The demons have no power to hurt or help. They are, as stones and wood, nothing before the invincible Might of Christ. To speak of a witch and her demons as if they could truly threaten one sealed in Christ is to grant them a dignity they do not possess. The warfare we wage is a good one, but it is not against flesh and blood, not against a woman who has called you on the phone. Our republic is at war with devils and incorporeal powers, and our Captain is God Himself.
Your prayer, though offered in Jesus’ name, reveals a soul that has perhaps forgotten the nature of this battle. The true warfare is not one of binding spells and counter-curses. The body is not evil, yet it can be made an instrument of unrighteousness through fear. This is the harder warfare, the internal contest where we require strong arms, sobriety, and continual vigilance. The enemy desires you to fix your gaze on an external threat, a supposed witch, so that you neglect the real struggle within your own heart: the struggle against panic, against a spirit of vengeance, against granting the demons more honor than they are due. For this same Paul, at whose name demons trembled, sewed hides in a tentmaker's shop. He did not run about binding every idolater he heard; he conquered by patient endurance, knowing the true fight is standing firm in faith.
You mention the phone call as if it had the power to defile you, but our Lord said, “Not the things which enter in defile the man, but the things which proceed out.” A voice on a phone, however malicious, has no power to stain your soul unless you receive it with a corresponding malice. The greater danger is that, like those at feasts who call on demons instead of giving thanks, you have been provoked to a kind of spiritual agitation that forgets your Master’s sovereignty. When God has nourished you with His good things, ought you to let a moment of human malice cause you to cry out as if abandoned? The dog, even starving, fawns upon its master. But we, who have received the abundant riches of His longsuffering, often bark at Him, seeing witches in every shadow.
Let this then be your warfare. Cease from endeavoring to command the ranks of demons as if you were their judge, and instead raise the trophy of a calm and trusting mind. The victory shines upon us not when we imagine we are casting out every hidden foe, but when we set our mind aright and are not overcome by fear, but overcome evil with good. The one who called you is to be pitied as a servant of a tyrant. Pray that she may be delivered from that cruel bondage, that Christ might show forth all longsuffering in her as He did in Paul. This is the truest weapon, formed not of harsh denunciations, but of truth, righteousness, and a peaceable spirit. In this battle array, you will find that those who plot against you war not against your frail humanity, but against the invincible Might to which you are united. Be at peace, then; do not seek for ease by trying to control the spiritual world through a word of power, but find your rest in the truth that no witch, no demon, no principality can snatch you from the hand of the Commander who has already conquered all.
