God is so wonderfully generous in his self-disclosure. He has not revealed himself to this race of rebels in some stinting way, but in nature, by his Spirit, in his Word, in great events in redemptive history, in institutions that he ordained to unveil his purposes and his nature, even in our very makeup. (We bear the imago Dei.) Psalm 19 depicts two of these avenues of divine self-disclosure.

The first is nature, or more precisely, one part of nature, the heavenly host observed and enjoyed by all of us. “The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge” (19:1–2). But just as ancient peoples manufactured complex myths to explain the sun, the moon, and the stars, the shame of our culture is that we manufacture complex “scientific” myths to explain them as well. Of course, our knowledge of how things really are is more advanced and accurate than theirs. But our deep-seated philosophical commitment to the notion of random, purposeless, mindless, accidental, “steady-state origination of everything is horribly perverse — anything to avoid the far more obvious conclusion of a supremely intelligent God capable of spectacularly wonderful design. The evidence is there; the celestial host “pour forth speech; night after night they display knowledge.”

The second is “the law of the LORD”: perfect, trustworthy, right, pure, righteous, radiant, reviving the soul, making wise the simple, giving joy to the heart, enduring forever, more precious than gold, sweeter than honey, warning, promising great reward (19:7–11). Here too we manage to trim and silence what God has revealed. Great scholars invest wasted lives in undermining its credibility. Many people choose snippets and themes that soon constitute a grid for eliminating the rest. Cultural drift constructs new epistemologies that relativize God’s words so that they are no more revelatory than the source documents of any other religion. Worst of all, Christians invest so little time and energy in learning what they claim to be the Word of God that it falls away by default. Yet it remains an unimaginably glorious revelation.

Leviticus 16 depicts another avenue of revelation. God graciously instituted an annual ritual under the old covenant that depicted fundamental principles of what he is like and what is acceptable to him. Guilty sinners may approach him through a mediator and a blood sacrifice that he prescribes: the Day of Atonement is both ritual and prophecy (cf. Heb. 9:11–10:18).

Respond with the psalmist: “May the words of my mouth and the meditation of my heart be pleasing in your sight, O LORD, my Rock and my Redeemer” (19:14).
