It was not every oil that might be used in the Lord's service; neither the petroleum which exudes so plentifully from the earth, nor the produce of fishes, nor that extracted from nuts would be accepted; one oil only was selected, and that the best olive oil. Pretended grace from natural goodness, fancied grace from priestly hands, or imaginary grace from outward ceremonies will never serve the true saint of God; he knows that the Lord would not be pleased with rivers of such oil. He goes to the olive-press of Gethsemane, and draws his supplies from Him who was crushed therein. The oil of gospel grace is pure and free from lees and dregs, and hence the light which is fed thereon is clear and bright. Our churches are the Saviour's golden candelabra, and if they are to be lights in this dark world, they must have much holy oil. Let us pray for ourselves, our ministers, and our churches, that they may never lack oil for the light. Truth, holiness, joy, knowledge, love, these are all beams of the sacred light, but we cannot give them forth unless in private we receive oil from God the Holy Ghost.
