Healing comes by the hearing of faith, and by that same faith peace is received, the peace of God which passes all understanding. Did not our Lord Himself ask, "Have faith in God?" This is the mother of the prayer, "Increase our faith." You have already some faith, else you would not ask at all, and it is with faith that we ask for faith. The least faith in Jesus is the gift of God, like precious faith, though it be not like strong faith. If you have faith as a grain of mustard seed, you can do wonders.
Pluck a leaf of this Tree by your poor trembling faith, the very leaves of Christ are for the healing of the nations. The least thing about Him is full of healing virtue. When guilt lies heavy and the hand of God seems to break into pieces, it is grand faith that can say, "Wash me and I shall be whiter than snow." Yet that is the faith which brings perfect restoration. When the prodigal returned, he was to his father as if he had never gone away. So shall it be with your son: the Lord will restore him, body, mind, and spirit, as though he had never known this affliction.
That touch of personal faith brings peace to the soul. Pardon and healing are one in Christ. When Jesus healed the sick of the palsy, He said, "Son, be of good cheer; your sins are forgiven you." So healing and forgiveness are placed in happy conjunction. If you will not trust God, neither shall you have peace. But let the blood of Jesus whisper peace within, peace, perfect peace, because his mind is stayed on the Lord. Bear this sorrow with Him, and then see what peace you will enjoy, even with sorrows surging round.
The Son of God looks upon your son even now. That divine look did the deed for Peter, restoring him after his fall. So a look from Christ severs a man from the crowd and works a saving repentance. Therefore, take the shield of faith above all. It quenches every fiery dart, from Satan, from wicked men, from one's own wicked self. Faith protects the conscience with the full assurance of atonement. Be resolved to hold on to your faith in your heavenly Father. The devil says, "If you are the son of God," but yield not to his "if." This is the way he attacked your Savior in the wilderness.
By faith the Red Sea was dried up; by faith the walls of Jericho fell down. Now let faith and hope grow. Healing leaves change the lifeblood, affect the spirits, and make the nature other than it was before. Your son shall yet be whiter than snow, fresher than a newborn babe, owing his restoration to the healing leaves of that Tree. Ask and it shall be given; seek and you shall find; knock and it shall be opened. The blood of Jesus Christ His Son cleanses from all sin and brings with it perfect wholeness. This world is ours, and worlds to come; earth is our lodge, and Heaven our home. Walk on, then, with the shield uplifted, bearing the blood-red emblem of the Cross. On, champion, on.
