The cry of a parent for a child pierces the very heavens, and be assured it has entered the ear of the Lord God of Sabaoth. You have not cried to a pitiless sea nor to the unhearing winds, for your God is a living God, and He will never leave you to imagine that His arm is slack to save. The darkness that seeks to swallow your son is no strange thing to that great Shepherd who watches over Israel. Remember, it was at noon that a strange darkness covered all the land when our Lord hung upon the tree, bearing the very curse that belonged to the abuse and violence of sinful men. That darkness was a pavilion of thick clouds, shielding the sacred person of Christ when He was made sin for us. So too, the darkness that now threatens your son, whether through the malice of others or the gloom of his own spirit, is not beyond the boundary of the divine dominion. "He has delivered us from the power of darkness", that is the triumphant note of all who are in Christ, and it is the sure ground upon which you stand to intercede for your child.
Think upon the nature of that delivering mercy. It came, and comes, when the Lamb is slain. All the dark powers that rant and rage in our world have already met their conqueror. They are fallen spirits, cast down to hell, reserved in chains of darkness unto judgment. Yet before the ransom was found, not of silver and gold, but the precious blood of Christ, what hope had we? God spared not the angels that sinned, yet for guilty sons of Adam He devised a way, yes, He found a ransom. Will He who laid heaven’s brightest jewel upon the altar to redeem us from all iniquity, now shrink from sending a common mercy, the bread and water of daily protection, for your son? It is a small thing for the Lord who gave Egypt and Ethiopia for His people, who gave His own Son for them, to dispatch a legion of His holy angels to build a hedge of fire around a trembling lamb. He who brought Israel out of Egypt with silver and gold, and not one feeble one among their tribes, is still the God who makes His deliverance effectual.
You cry for peace and strength to fill your son. Know this: the very darkness itself is often the schoolroom of God's most precious teaching. Though He were a Son, yet learned He obedience by the things which He suffered. Our Lord went into the dark to save the guilty, and He leads His own children through their nights of weeping that they might follow Him in complete trust. It is in the thick darkness that He meets with us, as He did with Israel, speaking out of the deep obscurity to write His statutes on our hearts. His plants often grow fastest in the shade. So, while you pray for the light to break, do not despise the sovereign purpose of the hour if it must tarry. God blesses the darkness to His chosen for their education and for their greater usefulness to others. Your son, groping in the gloom, may become a polished shaft hid in the Master's quiver, ready at the appointed time to be launched against the very powers of darkness that now assail him.
Let your faith take firm hold of this: the darkness shall not triumph. The present battle, however fierce, is as nothing compared with that dread conflict when all the dense battalions of hell hurled themselves against the Almighty Son of God, and were shattered forever. The iron bar of your prison, whether it be of physical abuse or spiritual oppression, cannot hold fast when the Liberator speaks the word, "Show yourselves." Yes, come out into the light, you that sit in bondage! Your son must be brought forth, not by any strength of his own, but because Jehovah says, "You are My servant, in whom I will be glorified." God will not suffer His Son to have spent His strength for nothing and see the ransom price wasted. Even now, though you cannot trace His hand, the moment of deliverance is fixed in the eternal purpose. The clock of mercy has struck in the courts of heaven, and the time has come. Rest your anxious heart upon the immutable promise: neither death nor life, nor angels, nor principalities, nor powers, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord. That is the stainless shield which covers your son today. Wait for it, watch for it, believe for it, the light of the undying Son of God, who lives forever, will scatter all the darkness, and you shall yet draw water with joy out of the wells of this salvation.
