The blessed person is someone who delights in the law of the Lord. He or she is very happy with that. After all, God’s Torah is something beautiful. It contains much more than commandments, for in it you discover the wholesome teaching of the Creator. You also learn how God directs his people in this unruly life so that you end up well. As the wise Solomon once wrote in Proverbs 1:2–3, To know wisdom and instruction, to understand words of insight, to receive instruction in wise dealing, in righteousness, justice, and equity.
And especially Proverbs 1:7, “The fear of the Lord is the beginning of knowledge.”
That is why we are encouraged to delve into God’s law (God's Word) and study it daily. This is also explicitly and strongly encouraged in Deuteronomy 6:4–9.
It is not for nothing that this has been the creed of Israel for centuries. The orthodox Jew, at the beginning of a new day, wraps the leather prayer straps (tefillin) around his arms and around his forehead. And the small leather box (containing Deuteronomy 6:4–9) has a set place on the doorpost of his house. It is always seen as a reminder of God’s wholesome law. For that law of God is so beautiful. Psalm 19:7–11 is rightly exuberant about it. It says a lot, that Psalm 119 (by far the longest psalm of all) is a song of praise for the law. The Jewish feast of Simchat Torah (= Joy for the law) is therefore the most joyful feast of all days of commemoration.
As Christians, we should not forget that Jesus once said (in Matthew 5:18): For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.
Of decisive importance here is to keep in focus the intent of the law—a way to grow in one’s awe for God—and to remember that intense studying of God’s law (Joshua 1:8).
2 but his delight is in the law of the LORD, and on his law he meditates day and night.
