For thou art my lamp, O Lord: and the Lord will lighten my darkness. (2 Samuel 22:29)
Am I in the light? Then Thou, O Lord, art my lamp. Take Thee away and my joy would be gone; but as long as Thou art with me, I can do without the torches of time and the candles of created comfort. What a light the presence of God casts on all things! We heard of a lighthouse which could be seen for twenty miles, but our Jehovah is not only a God at hand, but far off is He seen, even in the enemy’s country. O Lord, I am as happy as an angel when Thy love fills my heart. Thou art all my desire.
Am I in the dark? Then thou, O Lord, wilt lighten my darkness. Before long things will change. Affairs may grow more and more dreary and cloud may be piled upon cloud; but if it grow so dark that I cannot see my own hand, still I shall see the hand of the Lord. When I cannot find a light within me, or among my friends, or in the whole world, the Lord, who said, “Let there be light,” and there was light, can say the same again. He will speak me into the sunshine yet. I shall not die but live. The day is already breaking. This sweet text shines like a morning star. I shall clap my hands for joy ere many hours are passed.
