Psalm 119 is the longest of all the 150 Psalms and, perhaps for that reason, its 176 verses are seldom or never read completely either in public or in private meditation or study. This is an immense loss. It has a great subject: the Word of God. It shows how that Word is a treasure trove of spiritual resources for the highs and lows of the Christian's journey through life. At the moment of conversion every Christian is enrolled as a student in God's school, and finding this treasure requires daily Bible study. Meditating on each day's reading helps promote growth in spiritual maturity, experience of spiritual renewal, and the Holy Spirit can maintain praise to God in a continuous spiritual revival.

The Psalm obviously expresses the hopes and fears of a faithful Jew, but what is in it for those under the new covenant? The authors emphasise the practical lessons from this Psalm, in order that every reader might come to share their delight in the daily reading of the Word of God and the blessings this brings.
