This old troubled world desperately needs light to find the way out of its darkness and truth to rightly plan its future. But they must be God's light and God's truth, not the seductive lights and humanistic philosophies of man's fabrications.
God has, indeed, already sent out His light and His truth, but "men loved darkness rather than light" (John 3:19) and, although they profess to be "ever learning," they yet are "never able to come to the knowledge of the truth" and, in fact, "turn away their ears from the truth" (2 Timothy 3:7; 4:4).
That was true in the psalmist's day, and perhaps even more so in our day, although we surely have far more light and access to truth today than the psalmist ever had. We now have, for example, God's complete written Word (Genesis through Revelation). Another psalmist had promised: "Thy word is a lamp unto my feet, and a light unto my path" (Psalm 119:105), and also had promised, "For the commandment is a lamp; and the law is light" (Proverbs 6:23).
God's truth surely is what we need--in fact, all we need--for our faith as we look to our future. This also is revealed in the light of His Word, both His inspired written Word and His incarnate living Word. The Lord Jesus not only claimed "I am . . . the truth" (John 14:6), He also prayed for us, saying: "Sanctify them through thy truth: thy word is truth" (John 17:17). And for all who believe His revealed truth; "God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ" (2 Corinthians 4:6).
