This second parable compares what was lost to a drachma. It is as one out of ten, a perfect number and of a sum complete in the accounting. The number ten also is perfect, being the close of the series from the unit upwards. This parable clearly shows that we are in the royal likeness and image, even that of God over all. I suppose the drachma is the denarius on which is stamped the royal likeness. We, who had fallen and had been lost, have been found by Christ and transformed by holiness and righteousness into his image…. A search was made for that which had fallen, so the woman lighted a lamp…. By the light, what was lost is saved, and there is joy for the powers above. They rejoice even in one sinner that repents, as he who knows all things has taught us. They keep a festival over one who is saved, united with the divine purpose, and never cease to praise the Savior’s gentleness. What great joy must fill them when all beneath heaven is saved and Christ calls them by faith to acknowledge the truth? They put off the pollution of sin and freed their necks from the bonds of death. They have escaped from the blame of their wandering and fall! We gain all these things in Christ.
