Mark 10:52
And Jesus said unto him, Go thy way; thy faith hath made thee whole. And immediately he received his sight, and followed Jesus in the way. And Jesus said unto him, Go thy way; thy faith hath made thee whole. And immediately he received his sight, and followed Jesus in the way.
Jesus healed blind Bartimaeus because of his faith, so that he immediately received his sight and then followed Jesus in the way. His calling to Jesus as Son of David for mercy shows how the sick are brought to Jesus as the great Physician in the arms of faith. His cry came from a broken and repentant heart, throwing himself at the feet of Jesus without waiting for anything and without stopping to reason, even at the eleventh hour. His appeal shows that a person in need should go to Jesus for mercy without delay even when Satan tries to silence the plea, seeking Jesus rather than yielding to sin, despair, or anything that would keep the person from Him.
Spiritual blindness is blindness to the higher interests of the soul and to the blessed attractions of a heavenly life in the city of God. It is laboring for what is not bread, sacrificing peace and honor and the companionship of the children of God, even one's own children, to walk unhindered in one's own way, and striving to find contentment in secret sinful pleasure and base gratification without regard for God and heaven. Even when a person is hopeless and without God, Jesus of Nazareth still passes by offering what is most needed, something of infinite gain even if it cost the toil and suffering of a whole lifetime. Falling on the Rock Christ Jesus and being broken before it is utterly too late ensures the person will not be left to perish, for God touches the heart with new tenderness and leads to a sense of long-perverted obligations to Him.
The verse illustrates appealing to Jesus for mercy while He is near and passing by, so that those who awake and individually seek God and cry most earnestly to Him receive through grace clearer sight than they had, a gift more valuable than material riches, gold, silver, or precious stones. Applied to healing sought through faith, it means that faith appeals to Jesus as the great Physician for mercy and expects restoration, so that God's healing power is experienced as salvation while faith continues to look for fuller healing. Crying for mercy brings comfort and felt healing power by laying aside all medicine to rely alone on Christ, holding by faith for entire restoration and expecting to see and feel more of God's salvation, even restoration to sound the last notes of warning to the world.
