Overview

Isaac Watts's paraphrase of Psalm 119:9 ('How can a young man keep his way pure? By guarding it according to your word'), blended with Psalm 19's pairing of creation and Scripture. God's Word gives the young rules to keep the conscience clean (st. 1); it is sun by day and lamp by night (st. 2). The heavens and earth obey and display God's power (st. 3), 'but still Thy Law and Gospel, Lord, have lessons more divine' — the Word stands firmer than the earth and shines brighter than stars (st. 4). Its pure, everlasting truth will guide youth and support old age (st. 5).

Central theme: God's Word — Law and Gospel — as the sure guide for the young and support for the old, surpassing even creation's witness

Structure

Five common-meter quatrains. The young (1) — sun and lamp (2) — creation's witness (3) — the Word's greater witness (4) — youth and age (5).

Law & Gospel Shape

St. 4 names both explicitly: 'Thy Law and Gospel, Lord, have lessons more divine.' The Law guides and keeps the conscience; the Gospel gives what creation cannot.

Confessional Connections

Ps 19's structure: creation reveals God's power (natural knowledge, Rom 1:20), but only the Word reveals his saving will (Ap IV.5; FC V). 'Law and Gospel' — the two chief teachings of Scripture. The Law as guide to holy living (third use, FC VI) keeps 'the conscience clean'; Scripture's 'everlasting truth' (FC Rule and Norm). Training the young in the Word — the purpose of the Catechism (SC Preface).

Liturgical Use (Study Notes)

Confirmation; Christian education; Bible Sunday; youth services.
