You anoint my head with oil.
Recommended Reading: John 10:7-16
Over a hundred years ago, William Evans wrote a little book about Psalm 23, in which he said: “A shepherd must be a physician also. In the belt of the shepherd, medicines are always carried. Sheep are very susceptible to sicknesses of many kinds…. Ofttimes at night as the sheep passed into the fold, the shepherd’s knowing eye would detect that one or another of them was sick and feverish…. He would take the feverish sheep and… anoint the bruise with mollifying ointment.”
Olive oil was the shepherd’s great secret. He used it for making and dipping bread, for fuel for his lamp, as a lotion, and as an ointment for his own wounds and those of his sheep. A few drops of the lubricating fluid would relieve the hurt of a cut or bruise.
The Bible compares the Holy Spirit to oil. The Good Shepherd anoints us with this precious oil, and the Spirit’s invisible ministry to us gives us nourishment, brings a radiance to our face like a lotion, and heals our wounds.
Rely on the Spirit’s ministering work today.
The metaphor of oil—the visible and tangible liquid poured upon and absorbed by a human being—tells the invisible presence and action of the Holy Spirit.
