Psalms 18:28

Those that forsake the ways of the Lord, depart from their God. But though conscious to ourselves of many a false step, let there not be a wicked departure from our God. David kept his eye upon the rule of God's commands. Constant care to keep from that sin, whatever it be, which most easily besets us, proves that we are upright before God. Those who show mercy to others, even they need mercy. Those who are faithful to God, shall find him all that to them which he has promised to be. The words of the Lord are pure words, very sure to be depended on, and very sweet to be delighted in. Those who resist God, and walk contrary to him, shall find that he will walk contrary to them, Le 26:21-24. The gracious recompence of which David spoke, may generally be expected by those who act from right motives. Hence he speaks comfort to the humble, and terror to the proud; "Thou wilt bring down high looks." And he speaks encouragement to himself; "Thou wilt light my candle:" thou wilt revive and comfort my sorrowful spirit; thou wilt guide my way, that I may avoid the snares laid for me. Thou wilt light my candle to work by, and give me an opportunity of serving thee. Let those that walk in darkness, and labour under discouragements, take courage; God himself will be a Light to them.

"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.
