Send forth your light and your truth, let them guide me; let them bring me to your holy mountain, to the place where you dwell. Then will I go to the altar of God, to God, my joy and my delight. I will praise you with the harp, O God, my God (Psalm 43:3-4).
What a word of triumph! Now the psalmist understands what God is doing; He is driving him step by step to the ultimate refuge of any believer in any time of testing: the Word of God, which is the truth of God coupled with the light. The truth is God’s Word; the light is your understanding of it. The psalmist cries out for an understanding of the Word as he reads it and for light, which breaks out of these marvelous promises to encourage and strengthen his heart. He says, If you will do that, God, then my heart will be filled with joy and gladness, and I will praise you with the harp; for you, O God, are my God, my personal God. What a revelation that is!
