Charles H. Spurgeon on Psalms 18:28

"For thou wilt light my candle." Even the children of the day sometimes need candle-light. In the darkest hour light will arise; a candle shall be lit, it will be comfort such as we may fittingly use without dishonesty —it will be our own candle; yet God himself will find the holy fire with which the candle shall burn; our evidences are our own, but their comfortable light is from above. Candles which are lit by God the devil cannot blow out. All candles are not shining, and so there are some graces which yield no present comfort; but it is well to have candles which may by and by be lit, and it is well to possess graces which may yet afford us cheering evidences. The metaphor of the whole verse is founded upon the dolorous nature of darkness and the delightfulness of light; "truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun;" and even so the presence of the Lord removes all the gloom of sorrow, and enables the believer to rejoice with exceeding great joy. The lighting of the lamp is a cheerful moment in the winter's evening, but the lifting up of the light of God's countenance is happier far. It is said that the poor in Egypt will stint themselves of bread to buy oil for the lamp, so that they may not sit in darkness; we could well afford to part with all earthly comforts if the light of God's love could but constantly gladden our souls.
